One of my chickens started just staying in the nest box about a week ago. When I have coaxed her out she acted normal; ate, scratched around in the dirt, pecked around, but then when back to the box. When I try to coax her out she makes a funny trilling sort of sound and hasn't laid an egg since this started. Today I tried a warm bath in which she promptly pooped worrying she was egg bound. I'm at work now so I can't say if she's laid anything yet but I'm now wondering if she's brooding because she does seem to be flattened out in the box and I have noticed some feathers in there as though she's pulling them out to line the nest. I really do not want to have to try the lubing and inserting of fingers into her so any help or ideas as to what might actually be causing her to stay in the nest so much without laying would be greatly appreciated! Oh, I don't know if it makes any difference but she has only been laying eggs for a month and a half-two months, she was my last chicken to start laying eggs, all her eggs have been on the small side but well formed with hard shells. Thank you!
