I let one of my Australorps sit on a couple of eggs. She was great, and hatched out the two chicks. Ever since though she's not been the same. For a while I thought I was going to lose her. She would just sit on the floor of the coop. I separated her, gave her supplements and antibiotics, just in case. She seemed to perk up a bit, but not much improvement. I dewormed and dusted the entire flock. After almost a month decided she need to go back with the flock. She isn't AS mopey as she was before, but still not a happy hen. I often find her in a corner on the floor. She doesn't go to roost any more even though I have a ladder up there. She was sleeping in a nest box, now she just sleeps in a corner. When I let the birds out to free range she'll sometimes go out, but I usually find her in the run, once again just laying there.I watched her a few days ago come into the run from outside and she had a hard time getting over the 2 x 6 board (5 1/2"'s) at the threshold. She appears to be otherwise alert. Her comb remains shrunken though. I feel bad for her. I know it's not normal, but does it occasionally happy that being broody just takes too much out of them? Anyone else have a similar thing happen? Any advice? ETA: The chicks hatched out late June of last year.
