We've started to raise our own chicks which has proved to be quite a handful. We raised them from eggs and they have been doing really well. Recently we had a Coccidiosis outbreak as summer has just started here in Australia and two of our chicks died before we could identify and start medicating them. After we got them some amprolium they were perfectly fine.
However recently a chick in the group has shown signs of listlessness and has stopped eating and pooping. I smelt her mouth for 'sour crop' and she does have a beer-ish scent. I tried to induce vomiting by massaging the crop and holding her towards the ground and while she seemed to be relaxed about the whole occasion she didn't vomit at all, 10 minutes of crop massaging.
I've separated her from the rest and she's in a box with a little bit of yogurt and apple vinegar water. She's been showing these signs for two days now and doesn't seem to be improving. What do you recommend?
