I have done a search on this but can't find any info so apologies if it's a repeated Q.

My Polish Bantam boy is around 7 months old and for the past few days i keep catching him trying to climb on top of my Blue Orpington. Not sure he manages to balance up there long enough to actually do anything as she is twice his size.
 
My question is how old do the boys have to be before they are capable of fertilising eggs??
