Crop bound? I thought I had a hen that was just growing faster than the others, she was getting big, and eating a lot. Then I noticed she was waddling, her crop was what was big. When I picked her up she puked, gross stuff. I researched it and figured she was crop bound, did what they said online. Held her upside down and massaged and lightly squeezed every bit of PUKE out of her. Grass, hay and yuck. I thought she died once, even though I tried to give her plenty of air at one point she had a wad of solid coming out, I tried to lightly pull on it, she did the death flop, my wife said she was dead, I continued and eventually got it out. Gave her chicken cpr, and she came back, AMAZING! I didn't know if she would be OK, her crop was still stretched out. But a month later she looks and acts like any of my other chicks! Crop looks normal! I also fed her lotsa olive oil and greek yogurt after I emptied her this might have helped also. I don't know if this might be something that could be wrong with yours but thought I would let you know just in case. Good luck.
