We are 1 year and 2 months into keep a flock of chickens and over that time we had 1 clutch of eggs that were hatched by a broody hen. We learned our lesson today about roosters. We ended up with too many roosters (7 roosters and 20 hens). We were able to feed 3 roosters to predators but the other 4 roosters ended up being too much. Today a hen got a split side and it sucked! We shot the 2 big roosters with a 9 mm in the head and we are working on killing 1 more tomorrow. No more crazy crowing in the early morning and no more split hens. We didn't think we could kill chickens, but necessity is the mother of 9 mm's.
