I've been told to look for... smaller more symmetrical dot on head = pullet darker color = pullet darker leg's = pullet comb size..."obviously" lol ^^^^Especially for picking out pullet barred rock's Judging by what i have, i believe the black'er bellied chick with the slightly larger comb "i know, i know" is my girl. Where as the other one i bought is her brother :lol When i was looking closer, i could deffinatly see small tail feather's coming from our yellow bellied chick where as our darker bellied chick had next to none. So here is the break down.... chick 1.... Black belly Larger comb Darker feet Chick 2.... Yellow belly Smaller comb Slightly lighter feet A bit larger than chick 1 They both came from the straight run bin at my local RK. But the boy having a smaller comb is really throwing me off. So, what do you think guy's??? Im leaning pullet on chick 1 and Roo on chick 2.
