My son went to go pick up the eggs this morning and he came dinning in crying that our Roo was laying with his feet in the air dead! He was a little bloody on one of his wings. My question is did the hens kill him or did something else? We have 9 girls is that too many for one rooster? We are new chicken owners so any help is appreciated. We've had the rooster for almost a year but just got the girls this weekend.
