Aggressive RN

[flyte]

I have a RN dove who I would like to breed to one of my females. I have tried three different females for him to bond/mate with and he is very aggressive towards them and is so mean that I am afraid for the female since they are all so docile and then they become afraid of him. They want nothing to do with him (I don't blame them!) Is he ever going to bond with a female. I posted something similar to this topic before but since then I have tried everything. He had bonded to me but I have basically ignored him and feel bad. He still won't have anything to do with females. He definitely is a male so there is not question about his sex.
