My meekest (bottom of the pecking order out of 10) was found dead yesterday. No sign of injury and perfectly healthy the night before. My 8 month olds still sleep together and not on the roost (I think - based on where the chicken poops are). They like to be together at the corner of the coop. I know as chicks it is possible for one to be smothered at the bottom of a pile but is it possible for the same thing to happen to an 8 month old?
