I'm thinking blue. His mama is splash, and the roo that is in there is black. There was a splash roo in there but I re-homed him weeks ago (because he couldn't inseminate this exact hen!) and although there is a chance he is the daddy, it would be the longest of long shots, but hey, stranger things have happened. There was a blue cuckoo next door that occasionally breached the door but I don't think he got a chance to breed anyone... there was one morning that he spent the night in there though... now that I think of it... he was all bloodied the next day from mr BIG BLACK roo so I just figured he was beat to a pulp and never got a chance at any girls either, but then... there is a faint white spot on the head... the splash roo was carried a single cuckoo gene. I didn't want cuckoos, but if this turns out to be one... oh well, I'm KEEPING him anyhow, even if it is just to eat.
