Early morning the chick was fine, then a few hours later I noticed his vent area didn't have down on it. I watched him for quite awhile, and he was the only one pecking at it. I checked to make sure it wasn't blocked. The vent area all day has been contracting in and out or spasming. He only tried drinking on his own twice, and I never saw him eat. This is what I've tried: Just in case he was blocked up - gave a couple drops of mineral oil (about 30 minutes after that a little clear stuff with a touch of blood came out) Ran a little bit of water along his beak periodically Mixed chick starter with a little water and tried putting in his beak, but he wouldn't take any Sprinkled chick starter around him, but he wouldn't try any He keeps going in a corner and standing there until his head drops, and he falls partially asleep. He very rarely makes it all the way to the ground though since one of the others run into him, and he pops up. I've only seen him go twice more during the day, but it was pretty clear with a bit of a red tinge in tiny spots. Is there anything else I can try? Should I try to force the watered down chick starter in his beak? The other seven chicks with him and doing great, and he was also until this morning. We're new to all this, need help please.
