I have two 16 week old Rhode Island Reds one of them is significantly larger, with a larger/redder comb and seem to be the leader of the 6 total I have. I think it may be a room. What do Y'all think?
Naturally lighting and a full body pic that shows the whole bird without any hands or arms in the way will really help. The red comb at 16 weeks could be an indication of a maturing pullet.
Full body means from comb to tail and everything in between. Not a front angle that shows a hint of tail. Not a rear angle that shows an obscured comb. We want to see the whole thing.
