I have a Rooster (2yo) who is not what I would call virile.
He gets his favourite hen and that is about it....he leaves all the other hens 'wanting'.

My question is how hereditary is this kind of behaviour?
I have kept one of his cockerels and two pullets that he produced this year, as this is the breeding that I want to go on with.
They are only 3 months old now but I am wondering if the cockerel he produced will automatically be the same as his sire or if that is random?

I don't know if faithfulness is hereditary.

What happens when his favourite goes on holidays?

It depends what lack of fertility is caused by. Obviously fertility is a core requirement for perpetuation of the breed. However there are some fitness traits that affect fertility that are heritable, like rose comb affecting sperm survival. Inbreeding can have quite negative effects on fertility too, the underlying cause if that in highly I bred lines might be heritable. I had a Sebright line once that had adequate rooster fertility when young, but zero from two years old and older. That seemed to affect all the roosters, so was obviously highly heritable.

So yes, low fertility can be heritable I think.

Maybe fertility is the wrong word to use in this case? Perhaps libido may be more accurate.
People with other breeds don't seem to have the problem of the rooster not being interested, in fact, they have the opposite problem of the rooster being too active and wanting to mate with the hens on a regular basis.

I am thinking that the lines I have are possibly rather closely bred or if you like, inbred. I have hatched out some chicks from different lines (as far as I can tell) so I am hoping that by infusing these into my existing line I can help the situation.
