I have a Jersey Giant rooster named Odin, who is only 5 months old. I also have 8 hens of various ages. Every (and I do mean EVERY) morning, Odin makes sure he is the first one out of the coop. He has learned he can ambush a hen when she comes down the ramp, to mount her. I've actually seen him chase one of the girls for a good full minute before either catching her or start on someone else. I know a minute doesn't seem long but as fast as they run, I'm sure it could be compared to a Triathlon. After a while he calms down some and stops chasing so hard, but I have noticed him mount his two favorites several times in one hour or another if he can catch them. I have actually counted 4 times he mounted my BO in 2 1/2 hours while I was out improving their run. So I'm assuming this behavior goes on all the time. The girls are not bare backed (yet) but do hesitate to come out of the coop because of him. I'm still getting an average of 6 eggs a day, but I'm worried about their stress level because as I said he is only 5 months old and large. I'm thinking of a separate pin for him but hesitate because he is a good protector. When one of my hens got too close to the dog kennel (free ranging) and the dog lunged at her, Odin, at only 3 months old, ran and put himself between the dog and hen. Any time one of the hens makes a distressed scream he will come running with feathers all fluffed up ready for battle. I now have to be very conscious of where he is when I go to collect a hen for examination. Any advice would greatly be appreciated.
