Not a new member but haven’t been on in awhile and it seems my account was deleted. I need help in a big way!! I have been raising chickens for about 5 years and I have never had this happen. We recently moved from SC to Tennessee and I started my flock over completely. On Valentine’s Day I purchased 21 chicks and they all did great until 2 weeks ago. They are in a coop that was a storage shed with the previous owners and have about a 1/4 acre run that is only shared with a batch of broilers which stay in the chicken tractor. I have been through a lot with chickens in the past but I can’t figure this one out. My girls were acting normal and out of nowhere one died. Then over the last 2 weeks I have lost 4, including 2 today. The signs and symptoms are odd to me. Out of nowhere one will become lethargic and mostly stay Laying down with their tail end hiked way up in the back. I have noticed with a couple that they have diarrhea and their crop is very watery like sour crop. When I massage it to try and see if anything is stuck and get it out they do vomit. Anyone ever ran into this??
