I have (had) 15 Dominique chicks, now 4 weeks old. I put them in their new house last week, and two days later found one chicken dead. It had no tears in it's flesh and no missing parts, even the feathers were all intact. This morning I went out and there was another one dead, this time a rooster, same thing. What I first thought was that it had been partially swollowed by a snake and then regurgitated, because it appeared wet from the head down to it's shoulders (just above the wings), one wing was pulled upward, and the neck seemed stretched. I can't imagine a snake would try twice, considering the birds are not getting smaller. Thinking it must have come in while the door was open and the chickens were in the (enclosed) yard, I searched the house for hiding predators, but found nothing. The only entry into the coop would be through a 1 1/4 inch round hole where I have a electrical cord running, which is 4.5 feet above the ground. I've read that chickens will sometimes crush one another when panicked, but this chicken was in the middle of the coop, not in a corner, as was the first one. I'm baffled, any feedback is appreciated.
