You might want to read this, but, yes, it sounds like your hen had impacted crop. https://www.backyardchickens.com/ar...w-to-know-which-one-youre-dealing-with.73607/I have no experience with crop problems, but I wonder if a recent hen's death would be crop related. We have had a number of deaths, mostly chicks from the same hatch that I got from a breeder, and they had the same symptoms. For those chickens, I think one of our vaccinated hens sheds Mareks and the local chicks died from it. Lost 6 of 8 chicks at various ages. My hen who passed last weekend died suddenly. She seemed fine one evening, eating and acting normally. The next morning I found her out in the run, roosting on top of her feet but on the ground, shivering. Her comb was very dark and turning purplish in places, which indicates an oxygen shortage but she was not gasping or wheezing. Her crop was full and felt like a sand filled balloon, I could massage it a little but it was not soft at all. I got some water in her, did a little massage on her crop (upright position only), checked for a bound egg (none), then put her under the heat lamp. She died a few hours later. She had no sour smell and was eating just fine the night before. I took fecals in to the vet from our other chickens and everything was negative. Do you think this could have been a crop problem?
