Sour crop

[Chriswells2324]

Hello everyone. I’ve had chickens for years. I’ve never had any issues - disease, mites, etc. In the past month I’ve had 2 chickens who’ve developed sour crop. The first one went on to develop a crop impaction and died. It was my fault as I wasn’t paying close enough attention to the way she was acting. Yesterday I noticed another hen acting funny. Not rushing over to eat, tail down, staying away from the other hens. Her crop feels like a water balloon. I wasn’t able to feel much food in there, so I don’t think she’s impacted. She’s been isolated in a cage for about 12 hours now (over night). Her crop is still the same. She’s been drinking water (containing Hydro Hen) and pooping normally. I’ve read quite a bit on sour crop. Does anyone have any advice on anything else I should be doing? Also, I just find it strange that we’ve never had any issues and now 2 of my hens have been sick. Any help would be greatly appreciated!!
