It’s been about 1 week our longhorn is lathargic, not eating, pooping watery, and her red comb is turning black on the tips. I can’t get her in to the bird vet until Monday. I’m afraid she might die since she is not eating. She won’t come to me or reacts to her favorite treats. Help anyone come across something like this? We let her out on our yard and has her own pen. I’ve been keeping her in the pen because I don’t know if she ate a plant that might be toxic to her...any advice what might be wrong with her?
