I recently moved house, and took my 2 hens with me. For the first week they seemed to be doing ok, but now they are showing strange signs of possible illness. The house I've moved to already has 3 younger chickens, one of which I believe is a rooster. One hen (white) has become overly lethargic. One afternoon when I checked them for mites, I was able to hold her on the ground without even a slight struggle, and when I was finished checking, she stayed in the same place for over 10 minutes, looking to be falling asleep. The other hen (black) has been losing her feathers. I am thinking it could just be her molting, but I noticed she has also started walking strangely, as though she is losing her balance, and she is walking by crossing her legs over sometimes to regain balance. I've attached a few photos of both hens, though the white hen's symptoms are purely behavioral. If anyone has any idea what could be causing these behaviours and physical symptoms, please let me know. Thank you!
