I have a araucauna hen who is about 1.5 years old. She has been a somewhat regular egg layer until she went broody in May and since then didn't begin laying again until two weeks ago. A few days ago we noticed she was acting strange. She was getting spooked more easily when we were around. Now for the past few days she is walking around somewhat hunched over with her tail down. She also has very runny stool that is a very bright yellow/green color. When she walks, she looks like it is very uncomfortable as she is lifting her feet carefully and then slowly placing them down. The strange thing is that she continues to run (as best she can) around the yard with the rest of the flock. She does not have the same energy and is not pecking as much as the others though and hasn't been dust bathing. She also eats all of the treats that I throw out to them and I offered them a bowl of milk which she also drank. She also seems a bit out of it. I had to show her where the milk was. Last night she also couldn't get up to the roosts. She was looking up like she wanted to fly up but she wasn't attempting to do it. Finally she climbed up the ladder in the coop and slept at the top of the ladder/ramp. She also seems to have a lot of feather loss under her wings. It looks like there are quills sticking out. But that is the only place where I see feather loss. I don't think the others are picking on her because she has always been one of the feisty one and even this morning was "growling" at one of the other hens. Could this be a molt? Do you think she has worms? Egg bound? Suggestions? anything would be appreciated!
