It is very docile, I haven't seen any roo-like behavior towards the other chick. I think it's still too little to fight anything LOL But just figured I'd see what people's thoughts were on the comb. I'll have to go back and see if I can find pics of my BO at 6wks of age to compare. I thought she was a roo for the longest time because of how her comb wattles developed quicker than the others.1/2 & 1/2 Comb looks like a pullet ...wattle looks like a Roo..what is its temperament ? Is it docile ? or did it fight you ? probably a pullet
