Is anyone else in NH having losses of younger birds to sour crop? I lost two cockerels over the weekend, both 10-11 weeks old. The only real symptoms they had were soup crop (foul breath, squishy, balloon-like crop) and general lethargy. They both died within 24 hours of me noticing symptoms. I have one other cockerel that has been acting lethargic but is still eating and plugging along normally otherwise. He hasn't developed the foul smelling breath or squishy crop like the other two, but he hasn't gone back to energetic behavior yet either. I was so upset, I was convinced that somehow I've been a terrible birdy-momma. I went around scrubbing the heck out of every feeder and waterer, and changing the bedding, and watching all the other younguns for symptoms. I haven't lost any more since that first two, but I was feeling so bad. Then I just happened to be talking to a woman at the store down the road who also keeps chickens. I told her about the sour crop, and she looked stunned for a moment, then told me that one of her other customers told the exact same story earlier today. So now I wonder what could be going around that causes sour crop? Or, could it be a feed contaminant, since most people in my immediate area probably buy feed from the same place? Or could it somehow be weather related, since we had a streak of unseasonably warm followed by cold and wet? It's a mystery to me, so I thought I'd ask if any of you are having similar problems!
