Hi again Cathie
OK I can see now why you are keen to get things started then, if you are approaching summer.
How old are your hens?
If the other cockerel was the more dominant one (crowing first) then he might have been the better one to move in with your flock as he would probably have found his feet sooner, but give this lad of yours some time and he should step up to the mark. It depends as much on your hens accepting him as on his own behaviour but we all know how attractive a trait confidence can be!
Do you give your chickens treats and if so, how does he react when you dish them out? Does he call the girls over and make a big deal out of showing them the tasty morsels he has "found" for them or does he just scoff whatever he can himself....in which case he still has quite a bit of growing up to do? Have you seen him drop a wing and shuffle sideways towards any of them or is he just keeping to himself. Has there been any interaction between him and the hens, not mating, but just general foraging together, dust bathing etc.? If you watch them daily you should start to see little changes in how they interact.
Personally I would rather have a cockerel that is a little slow in coming forward than an overly assertive one that is grabbing hens and aggressively mating them at every opportunity, pulling out feathers and ripping skin and generally stressing them to death... which is a problem too many people have in their flock..
It would be good if you would keep this thread updated with his progress as I will be interested to see how long he takes to win them over (or subdue them).
Good luck
