Ok I have had him for 8 weeks. he was pretty good sized when I got him but still a baby I think. He was in the process of feathering out. He is now the size of my 9 week old barred rock roo. I don't know how much bigger he will get. I say its a he so i won't get my hopes up. Of course i am keeping him regardless. I've been looking though and I don't see a comb. Little black skin at the top of his beak that I guess could be the start of one. So with silkies what am I looking for. Also are their roos a bit less agressive so I can have more than one together?
