Ok, so we have separated our girl with the sour crop, Gertrude. I brought her inside after they went to bed last night so she wouldn't freak out too much. I put a heating pad under a towel in the cage and covered the whole thing with a blanket to keep it warm and dark so she could warm up. We vomited her twice on Saturday and twice yesterday with a little success, but she didn't seem to improve enough to make me comfortable keeping her in with the rest of the girls and all that entails. I spoke with a (new) friend who has been keeping chickens for 20+ years and she said there's no harm in separating her and withholding food for a day or so while allowing her crop to empty as much as possible on it's own. She is awake and a little confused, but she seems alert and her crop has gone down about half way, but it's still very bulgy for first thing in the morning with no food since about 6pm yesterday. Her poops seem soft but fairly solid, as in, no watery poops. She has access to fresh water, I turned off the heating pad and put a desk lamp on top of the cage in one corner to give her warmth and light.
Now, where do I go from here? As you know, I'm very new to all of this but being "schooled" quickly by this flock ! However, if I were to hazard a guess, I think we caught this early enough and she's going to make a full recovery... I just want to do the right things from this point forward for her. So any advice or tips on what I should be doing now?!
