Sorry, I don't have a current pic of this bird, but I was wondering how big the comb gets if it is a roo? I have recently figured out that the 6 silkie 'chicks' I got at the auction this summer are probably about 7 months old, and I haven't heard any crowing!?!?!? I was thinking the single comb was a roo, but shouldn't it be crowing by now if it were? I'll try to get some current pics tomorrow, but was wondering if anyone can give me an idea? Thanks
