Hello all - I went out to put the chickens(9 hens and 1 rooster) to bed to night and noticed I was missing one chicken - Greg the rooster (19 weeks), so I looked in the run and there he was - dead. I looked him all over and there was no marks or anything. Any Ideas as to why he died?? Maybe a factor - One of the hens likes to fly out of the run and go into the yard all day. Was he stressed about this? Cheers!
