We ordered 26 and have lost 6. I feel like we're failing here. 6 were lost to predators we've fixed that. One was dead this morning no visible cause, another died at 4 days old, another this morning is holding one foot up and hopping, and the last is getting it's neck pecked at by the other chickens. They are various breeds, straight run from McMurray Hatchery. My daughters is the smallest, a silkie. I've seperated that one and the one with the bad foot or leg. All the chickens look healthy I have no idea what's wrong, why the one died. It did get down to 40 last night but there is a heat lamp. Any ideas? I know it's vague.
