Penny is almost 6 weeks old. I realize it's a little early---but when I see other people's RIR at this age- the girls usually do not have such prominent combs. Would you agree this is a little roo? Also- behavior wise- toughest bird ever. Walked right up to our Chihuahua, stuck the chest out, made the neck long and pecked the dog right in the nose a few times and chased the dog around. My husband may rename in Rambo.
