I am very new to raising chickens, I have only had mine for a month and I found one dead today...she was three months old, fed and watered everyday and I keep the coop as clean as a chicken coop can be...she did not have any marks on her, but her head was kind of tucked under her body with her legs out...the other two chicks seem to be ok, but so did the dead one yesterday, can anyone tell me what could have caused the death and should I be worried about the other chickens?????
