We just had a problem hatch this past weekend. We had a house sitter because we were out of town (bad planning!). He was raised on a farm and has been around all types of hatching birds, including chickens. We left specific written and verbal instructions, the most important of which was don't open the incubator once hatching starts. Well, the first 3 chicks hatched, and I think he opened the incubator to take them out. I think this because all of the other chicks had peeped, but were shrink wrapped and dead in their shells when we got home. This was our second hatch, and the first one didn't yield any dead in shell birds, and we did everything the same, so I feel like this is a logical conclusion to jump to.
My questions are:
1. One of the chicks seems to have a gimp leg. The leg looks fine, but the chick doesn't really put weight on it. The chick eats and drinks fine. Should we let it grow up? Will it get pecked on once we move them out with the existing flock? What's the humane thing to do? I'm obviously open to opinions!
2. All 3 chicks have what looks like poop stuck to their butts, but it hasn't moved at all all week. What is it, and is it ok?
Thanks so much in advance!!
