Where I live, that's not much of a concern.
I would agree.
Recently, I have an older hen that is having trouble getting up on the roosting bar, and back down again. So, she has taken up nightly residence in a nesting box. I have to clean it out daily now. But I feel sorry for the old girl, and unless I cull her, I'll have to live with her sleeping in the nest box. I think I will just use paper shreds in that one nest box because I have to clean the poo out daily and lose maybe 25% of the nest bedding in the process.
In her case, I know it's not just a bad habit. I watched her jump down from the roosting bar one morning and she basically did a hard belly flop on the coop floor. A few days later, she no longer went up on the roosting bar with all the other chickens. I have a few chickens that I expect might not make it through our cold winter here in northern Minnesota. She is on the short list.
