We had eggs from our second broody hen hatch a few days ago. She had decided to sit on the eggs herself, and we didn't catch her until a couple days later, so we let her sit on the nine eggs she had commandered. They had been laid over the past 1-2 days. Six of the chicks hatched one morning and then the next evening, a seventh chick hatched. That was 36 hours from the initial hatch. By then, the momma hen was out of the nest and was teaching her new babies how to eat, drink, etc. The poor chick that hatched late was laying there, damp, freshly hatched, and we hoped that the momma hen would jump back on the nest as nighttime came. It was a warm night - 90 degrees - so we hoped that the chick would be okay regardless. we didn't intervene. The next morning, the baby was dead. It was very sad to see it curled up and realize that it died from exposure since it didn't have the momma hen to keep it warm. If this happens again, should we do anything differently? Should we have intervened and put the baby chick under a brooder lamp? We don't use a brooder, since we're using broody hens, but we do have a brooder lamp from our initial chick purchase last year. We really thought the momma hen would get back on the nest so we didn't think we had to do anything. Now I feel awful about that decision.
