I had a sillkie chicken, I think it was a male, not 100% sure since it was only about 4 months old. He was in kind of close quarters with its siblings and they started pecking at one another, I think because I was using a white heat lamp instead of red. I switched to red a week ago and they seemed to be growing their feathers back (the ones that were being pecked at). So yesterday I went down to feed them and there was one dead. He didnt show any symptoms before hand (that I noticed). It was just lying there and its intestines were hanging out of its vent (probably like a total of 6" of intestines). How could this happen and what could cause it? Should I be concerned for the others? I inspected all the others and found one has white caked all around its vent. I feel bad because I have not been paying much attention to them, just feeding and watering everyday and making sure their area is clean and warm. (Just had my first baby 2 months ago so have been getting used to everything) Once this one died I inspected them and found this one. I tried rinsing it under warm water and rubbing it, most of it comes off but all around the vent it is like the white stuff is so caked on that as I tried to get it off, it wants to take skin with it. It looks swollen and red in the center. There is also some white kind of oozing out a little bit too. What could this be? I feed them layena medicated chick starter grower feed still. Please let me know what you guys think! Thanks.
