I have one chicken about 19 weeks old who appear to be bloated bigger than her flock mates all the same age, the crop also seems large and hard (I've done some reading on impacted crop) . She is eating and drinking and moving around but lays down in the run on the ground most of the time. She is also the only one of 11 that is suddenly sleeping on the ground while the others are roosting. She also kind of appears to be having a hard time swallowing. Been happening for the last day or two and not really sure where to start. Should she be separated, does this sound serious? First year with chickens. We also don't have a vet nearby that treats chickens. I don't have any photos or videos at the moment.
