herd an old wife's tail that if u put another cock next to him or were he can see it it will gee him up a bit
That certainly works and is used on commercial breeding farms if the fertility starts dropping, its known as spiking.
They add a few younger males to the mix which bucks the older guys into action!!
So bought a quite pricey Minorca cockerel at the National so had him since Jan.
Any ideas? everything else is doing it like its going out of fashion but I've not even seen this chap dance. anyone had this happen?
Has he been outside since you got him?
If he's been kept inside previously with low light levels it may take him a while to get into breeding condition, the light affects the males the same as it does the hens.
If you pick him up and sit him upright on your knee, then run your hand along his back quite firmly and give him a gentle squeeze as you get to the tail you should see the tail kick up and feel him flinch, this will tell you if he's in breeding mode, (its the first stage when doing AI) if he doesn't do it he's not ready or just infertile.
Try it with one of your known working males to see if you can spot the difference.
If he's ok it may be as Chris has said and the women are just making him feel inadequate
I don't know if you remember but I had a SG cockerel do the same last year, wouldn't mate with a hen at all, zero interest in mating despite trying him with many different hens in different locations and trying AI on him.
He eventually got going in mid summer after being housed with a flock of small bantam hens.
