Keep it if you can. Just keep handling him a lot so he'll like you and won't mind you coming near HIS girls.
After reading here at BYC's how great they can be, I was hoping I would ended up with at least one roo out of my ten pullets.
I have ended up with both of the EE's are roos. The one that started crowing with a horrible squack at 6 wks old is very sweet, always coming up to find out what treats I may have for everyone to letting me pick him up and pet him to the other who has always been my henny penny chick that never liked being picked up. So far, at 13 wks old he hasn't crowed and no problems with the two roos getting along.
Yesterday morning one of the BR's got out of the run when I was bringing in fresh water. I went out to get her and while I was pushing her in the door so the other's wouldn't get out, the nice roo came up and grabs the BR by the check and pulled her in.
I guess he was teaching her not to go out anymore. It was very funny to watch her run off shaking her head.
P.S. I live on 4 rural acres, so roos are ok. Which is a good thing because I no longer need an alarm clock. My little roo starts crowing just after 5 am for about 15-20 min then stops until I go out to let them out and I'll yell "where's my little rooster' while I'm heading to the coop and he'll start up again. Gotta love those guys.
