Malay Game - Mixing with a Black Australorp

Hi

Just wondering if anyone knows how I would go at keeping my Malay cock (The one on my avatar) with a black australorp hen? They have grown up together since little chicks. A strange combination I know but it is a story behind it.

Lenny .. who used to be Lucy, is having standing problems at the moment so is confined to a pet crate, I just found out he is a he which now complicates things.

I have heard that they do not crow as much as normal roosters is this true?
Will he try to mate with Penny my little one once he gets better? .. If he gets better.
They are very tame and get along very well but I now know that he is from an aggressive breed will he change and attack her, he protects her now very cute.
He has plenty of room to roam and will get his exercise but I am worried about the hen.

Any info would be helpful and some info on what to feed them would be great, I know they need high protein diet but what do I give him apart from boiled egg and vegy scraps?
