I have a group of chicks that are supposed to all be pullets but my RIR is larger and more aggressive than the rest. Also her/his comb is starting to turn red as are her/his wattles (my ISA Brown and Leghorn still have very light colored combs). This is my first flock and I would greatly appreciate your help. I have two pics, one of just the chick in question and one with said next to the California Grey Leghorn and Silverlaced Wynadotte that are the same age (8 weeks today ) for comparison. Thanks!
