Ok, this is the scoop... My 1 1/2 year old RIR named Rosie (sounds silly, but I'm assuming it's a gender confused rooster... never laid an egg, tried a poor attempt at crowing when s/he was 14 months old, not really since) has a large lump in his chest area. This is directly in front of him and, if walking around, would be the first thing entering a room... it sticks out in front. Not in the neck. Not down between the legs. Just a huge bump the size of a small baseball in front. It is basically centered, but ever very so slightly off towards his right side. I'm guessing this is the crop. Am I right? The skin is pretty stretched tight across the lump and I think I feel chicken feed in there, but not sure. I don't want to press too hard. I did try massaging and he did not move away. His personality is much quieter and slower than usual; I think getting a bit weak. I've seen posts on olive oil, apple cider vinegar, yogurt... which should I try? I also saw posts on crop surgery, which I'm a bit scared to try. I'm going to try gently giving him olive oil now from a dropper since that doesn't seem to do any harm and see if that does anything. Am I looking at an impacted crop? I know pics would help but I don't have any to post. His comb is droopy to one side. Started seeing him acting "not himself" about 5-6 days ago. Noticed a bump a couple days ago. I thought he was just losing weight so the chest was more protruding, but my husband thought it might be an enlarged gizzard. This is our first flock so I'm not going to say either one of us knows exactly all the chicken's parts. Thanks for all your help!!!
