On the long weekend we noticed one of our ISA browns was not well. She was a bit fluffed up, not foraging and lethargic. After a bit of investigation and googling we thought she might have sour crop? We gently flushed out her crop according to directions I found on the net. Since then we have been feeding her a little oat bran mixed with good home made yoghurt and a bit of apple cider vinegar. This morning she looked a bit brighter and I soaked some Barko dry dog food in warm water, mixed some yoghurt in and also gave her some soft ripe tomato. She was more interested in eating which was encouraging. Hope I am doing the right thing. Any thoughts?
