One of my hens has sour crop. I've had her isolated for about 5 days now. She has the typical "nasty chicken butt" so I've bathed her a couple of times. I've been feeding her a little yogurt (which she isn't eating anymore) and I put 2 tablespoons of ACV in a gallon of her water. She is just picking at food, not really eating much. My husband and I just tried to flush out her crop several times with the ACV water. She puked up a bunch of fermented scratch and other yucky, smelly slimy stuff but I thought we killed her the 3rd time we got her to puke because she went limp and just laid on the ground for a little bit before she started breathing again and slowly came back to life. I'm letting her rest now with no food, only water, but I don't think we got her crop completely flushed out because she was still puking yucky stuff, not clear liquid. Do I let her rest overnight and try flushing her crop out again tomorrow or let her be for a day or so and see if she's better? Any help would be appreciated.
