Hay! In need of some advice as I've never come across this before in a chicken. I have a 4 year old hybrid whom was fairly active until a few weeks ago, she now just lazes around in the sun, sleeps and doesn't really run around the coop anymore, she just sits with her tail and head down. She's not egg bound, no blocked or soup crop, no worms, no other signs of Infection. She eats well and responds to treats. She is getting thin and her breastbone is quite pronounced. Any ideas? Thanks
