I have a leghorn, who is 2.5 years old. She had a fairly hard molt in terms of feather loss compared to the year before. She was my last one to molt, which started in late October. She now seems to have all of her feathers back but over the last few weeks, I have noticed her distancing herself from the other chickens. She also started roosting on the landing of the ramp up to the roost for a bit but now sleeps on the floor of the coop tucked in a corner next to the nest box. I think she moved there as she likes to go to bed before the others and they were disrupting her on the ramp making their way up to the roost. I have also noticed that if she gets bumped by another chicken, she looses her balance and sits down. She is eating, drinking, grooming normally and her poop looks normal. Her comb is shrunken and pale but it did this last year when she molted and so did my other leghorn. The other leghorn molted a little before her and fairly hard compared to last year and her comb is just starting to get color and growing larger. The one that is having issues has been the top chicken in the pecking order. Any suggestions would be great.
