Hello. First year poultry farmer here. We have lost 6 (one month old) chicks out of 55 since we moved them outside to the chicken tractor last weekend. 5 died at once and looked like they got struck by lightning, meaning they were close to each other and flat. I'm thinking maybe they smothered one another when they got cold? Then we lost another one today for no apparent reason. My question is: is it typical to lose this many chicks? I feel bad and wonder if we are doing something wrong.
