Is there a way to keep hens from soiling the nesting boxes?

i dont think so

because ive heard u cant toilet train chickens, unlike dogs or cats

and apparently 1/2 of the soiling is done at night or during thier sleep
so yeah

i have to clean my coopa quick clean every day.

 

If your chickens go out to a run or to free-range and are not in the coop all day, I'm gonna assume that she is messing up the nest box by roosting on it at night.
Make sure your nest boxes are lower than your roosts and make sure you have enough roosts for everybody. It may be necessary to go in the coop at night for a few nights and move the hen from the nest box and put her on a roost. It'll usually click in their heads to use the roosts, but it can take several days of moving her at night.

 

Ha! I bet she is telling you she doesn't like the schedule being stuck inside! I don't know of a solution short of closing off most of the nesting boxes. Maybe others would kick out the offender when they needed to lay..... Sorry for the yucky problem. I have worried about this happening.

 

can u post a pic of your coop or your set up?

ive actually accomplished mine to sleep in the nesting boxes in the coop...

but yeah the soiling...thats just a part of thier nature..
they are not cats, dogs...
they are slightly simplier than them.

 

just wondering if she has done this ever since she started laying, or has it just started?

Maybe she has a "tube" problem - lays an egg, and then can't hold back the pooh or something?

 

This problem was brought up not too long ago. Maybe this link will give you more people's comments and suggestions:

i have a kind of odd thing going on in mine right now...they are using only one nest box as a toilet. there's barely (although, yes, some) any poop anywhere else in the coop. they are using the nest box closest the door as a ...well, for lack of better terms, a cat box.

 

I would remove the nest box being used a a water-closet.
