Two days ago we had a chick completely disappear from our coop/run area. There was NO sign of him. There are no holes in my enclosed chicken run, or coop except one about 5 feet up where a darn pumpkin vine snaked up and forced it's way in, it measures about 1.5 inch. Even though none of the 5 children at my home during the incident admitted to entering and possibly leaving the door open, I was learning towards one of my kids in particular as the cuprit. She was the only one whose whereabouts I was not sure of at the time, and she is not a trusty worthy little girl and often does things without permission knowing she is not supposed to. Anyway, fast forward to this afternoon. I put the little 1 week old chicks outside in the run/coop around noon. An hour later I went out to put ice in the larger water tin I keep out there (they like to play with it) for the big chicks and bring in the babies since I was leaving the house and don't leave them out when I'm not home. I only saw 3 little chicks pecking around (the big ones were in there as well but they stay away from the littles) and looked around to find one of the little chicks curled up, dead, covered with ants and missing his head and a foot! I had to compose myself before I could go back in the house, walking past 4 kids to get what was needed to remove the chick from the coop. I am horrified! The temp in the run was 86 degrees. It's been in the 100's for a couple weeks, and I keep the chicks cool with ice, and misting and a fan. I don't think he overheated, but maybe? But then what about the missing parts? Could ants have done this in less than an hour, could the other chicks have pecked at him? None were around him when I went out there. If it was a kid that let out the first one, I know for sure it wasn't a kid that did this to the chick today. They were all in the house with me watching a movie. Any idea's? I'm really freaked out here.
