Signs you have Mice in the Chicken Coop

Your hens don’t want to go in to roost at night

If your flock doesn’t want to go into the coop at night to roost, they might be trying to tell you something is wrongIt’s time to check for the M & M pest pair. Mites and Mice!

Finding mouse poop

Check every few days by raking the bedding in the corners and examine the nests for any sign of mice droppings. You’ll most likely find them in corners, against the walls, near the feed, and on shelves.

Bags of feed or treats chewed open

This is a tell tale sign of mice or rats in the chicken coop. Check your feed bags and treat bags bags frequently for small holes, or better yet, keep them in steel containers to keep out rodents!

Finding mouse nests

Mice love to nest in quiet, private spaces. Look for their nests in unobtrusive places, like corners, shelves, underneath and inside of stored objects.

Mouse nests in chicken coops usually have a lot of stashed chicken feed, feathers, and fur.

Is it really a big deal if the chickens and mice co-habitate?

Yes, it can be harmful to your flock because mice carry many diseases. They also eat and taint your chickens food source by using it as a kitchen and a bathroom both.

You may have noticed one of your hens eating a mouse that it found.  That is not uncommon but can be another source of danger.

The mouse could have eaten poison from your own farm or a neighbors, or have a disease which is then transferred to your hen.

How to Get Rid of Mice in the Chicken Coop

Have you found the telltale signs of unwanted whiskered visitors? What do you do now? Removing unwanted guests is the first step.

Lethal Traps

Traps are safe for your flock and the local wildlife, but you need to place them out of reach by putting them in a containment box.

For an economical choice we’ve found the Snap-E Mouse Trap to work well, and it’s usable again and again. The only big downside to this trap is the gory aspect of releasing and disposing of the dead mouse.

The Goodnature automatic trap  is another awesome choice for getting rid of rodents in the chicken coop.

This trap kills the mouse instantly with no poison or risk to your chickens. It is a little bit of an investment, but we believe this trap will last a very long time, and it auto-resets over and over.

The best part is the dead mouse can be safely eaten by your chickens or local wildlife!

Live Traps

Colony traps are small metal boxes with a one-way door. An entire family of mice can enter the box, and you can safely relocate them.

The Ketch-All Mousetrap is a great option for catch and release, and it has a clear lid so you can easily see if you’ve caught a mouse or not!

Poison

Poison should only be used as an absolute last resort.

To be completely honest, we don’t recommend this course at all, but put it in here in the case that absolutely nothing else is working.

Poisoning mice is a risky business, as you never can tell where the dead mice will end up. Additionally, poisoning is a slow and painful death for the rodent, and it’s certainly not the most ethical way to get rid of pests.

If they die within reach of your chickens, and they decide to eat the dead mice, your chickens will be poisoned too. Alternately, if the dead or dying mouse is eaten by a wild animal like an owl, it will poison that animal as well.

If you do decide to use poison, it should only be placed in containment boxes so that your chickens can’t reach it. If consumed by your flock it could be deadly.

After you get rid of the mice, thoroughly clean the coop by taking out all the old bedding from the floor and nests removing as much of the mouse’s belongings as possible. Scatter new bedding on the floor and in the nests.

Note: Glue traps should never EVER be used to get rid of mice. Glue traps are inhumane in every way. This is not only a very slow and terribly painful way to die, glue traps often inadvertently catch and kill many other creatures, including song birds, snakes, frogs, toads, butterflies, and bees.

How to Prevent Mice in the Chicken Coop

Now the mice are gone, but how do you keep it that way? You don’t want another family of mice to move in!

Look for holes in your coop

A mouse only needs a 1” hole to enter. Cover every opening including the vents, windows, etc. with ¼ inch hardware cloth on the outside of the openings, preventing any access from chewing through the wood.

Place all feed in a steel can with a lid

If you stop feeding the mice, they’ll find another home. The biggest reason you have mice in your coop is because they get a free buffet every day. Keep your feed and chicken treats in a steel bin.

Remove food and water at night

As we said before, chickens sleep soundly and do not eat and drink in the night. You can safely remove their feeder at night and bring it into the house. Mice love to eat while your chickens sleep, so it’s essential to cut off all access to their food.

Plant mint around your coop or spray with a lavender mint spray

Mice hate the smell of mint, so it is a natural deterrent.

Adopt a farm cat

Even though the cat doesn’t enter into the inner sanctum of the coop, having it around the outside keeps mice traffic to a minimum. Many animal shelters have special deals on barn cats or “working cats” that prefer to live outside.

Now your bases are all covered, but it’s good to keep an eye out for any possibility of a return by checking the coop weekly for any new openings.

Here’s to a clean and healthy coop life for your flock!
