We have a light Brahma hen who we thought has been molting for the last couple of weeks. You can tell from the picture that she has lost feathers and is much smaller than our other light brahmas. I noticed that she has been laying down pretty often and I will catch her lying while eating or pretty much whenever she isn’t standing. I just noticed that her feet look swollen. I’ve never seen this before and I am looking for some advice on what may be wrong with her if anything at all. She acts, eats and drinks normally other than the limping that I just noticed today.
