I am so glad I found BYC! I have 3 chickens 2 1/2 months old. They all seem to be doing good expect for my Plymouth Rock. I noticed she had a big bulge on her chest. When I touched it it felt kind of squishy and when she puts her head down it sags and wiggles. I think it might be her crop, but the bulge has not gone down for a few days. She is on grower feed (mixed with leftover starter feed) and has access to greens all day long. I put some grit in the coop yesterday, but it didn't seem to help the bulge go down. I'm not sure if I should be worried, if it will go away on its own, or if I need to somehow intervene. I have heard of soaking bread in mineral oil and feeding it to her, but have also heard that some chickens need surgery to remove whatever is stuck. I would appreciate any advice, I'm really worried about her.
