I have a black austerlorp that was fine and the other night my husband came home from work let the girls out to free range. Myrtle was on the nesting box so he shooed her off. She came out of the run and just stood there with her right leg barly touching the ground. He offered meal worms to the flock and the next thing he knew she was with the rest of the group eating meal worms but doing this laying down. When they were done she walked over to the water with a little limp and everytime she stopped she would lift her right leg. That night she did not go into the coop but was found laying in a corner. Husband put her in the nesting box and that is where she has been ever since. We are in our second day of her laying in the nesting box. She is not eating or drinking. She is very lifeless. Her comb is not bright red but pinkish. She is pooping. Any information you have would be helpful. Thank you.
