My 3 month old chicken, we think is a rooster has a swollen right side. I just noticed he was all poofy so I picked him up and noticed his right side has a large soft spot, its pretty large. Is it just his crop? I gave them a small piece of bread as a treat today, does he need to just poop? More grit? My older rooster has a smaller spot but nothing noticable so I think its just the crop. Is everything okay?
