I have 2 rescued flocks that I quarantined separately for 2 weeks then introduced into my new coop. I have now lost 3 with now one chick I’ll. and they all share a couple of similarities. The three that passed were older so I assumed it was just old age. But now one of the chicks is sick. They just seem to get lethargic, seem to almost sound like they are gurgling water, ruffled feathers, and generally weak. I’ve checked their throats with no blockage. Been giving vit water for about a week now and it drinks a lot and is still eating. They do have a run in a very forested area so lots of foliage they can get into. Any thoughts would be good. I’ve had their poop tested with no parasites showing. I wanted to attach a video but can’t seem to do it?
