I'm dealing with diarrhea here in one of my birds. The others seem fine. She is pooping a lot of water. It's been going on for about 36 hours. She is 21 months old. She was just wormed for the second time 11 days ago. She is vaccinated for Marek's and coccidiosis. Her appetite seems fine and she is drinking well. I've given her some plain yogurt as well as electrolytes, in addition to mixing up some "exact" baby bird food (paste consistency. She gobbled it up) as of this afternoon. Is there anything else I can try? Her tail is up and she looks okay. I noticed she is starting to molt today. Could that be part of it? *I wanted to add that she hasn't laid an egg for months. She seems to enjoy pecking out the feathers just below her vent, so she's been lacking in that department for a while. I've checked for parasites and never seen anything on her or any of the others (who all seem fine). I did feel around for anything abnormal but didn't notice anything.
