I have an ee hen, Banilla, that successful hatched a chick over the summer. I thought she was going broody again (puffed up, sitting in a box all day, pecking at me when I would try to move her), and I thought she was nuts, because it's January and we are in Wisconsin. When I got a closer look I noticed she was loosing neck feathers, just on one side. They have already been through their molt, or so I thought. I checked her rear for lice and didn't find anything, but did notice she is missing lots of feathers on her belly/breast. She is acting strange - she will sit in a box as if brooding, but no longer pecks at me when I go at her. Sometimes she just looks puffed up but is on the roost. She cocks her head a lot, as if (were she human) confused. I saw her eat and drink today. I do not think any of her mates are pecking her, she just seems thin, raggedy and ill. Also, she must have broken an egg and has some yolk stuck to her belly - she is known to steal eggs from her mates and put them under her, and occasionally the eggs don't make it. All of the other 7 hens and 1 rooster we have are healthy. I am in Western Wisconsin where it has been horribly cold (well below zero for our daytime highs) but we are coming out of it now finally. Any thoughts or advice greatly appreciated.
