Looking great! Ill have to get some updated pictures of my two young ones (forget age) turns out the one I was sure of being a pullet is a cockerel and the one we swapped is a pullet. So looks like ill be haveing a malines chicken dinner!
Looks like both are roos. I have the same thing going on with my 11 1/2 week olds.
These boys are the same age, yet the one above has more developed comb & wattles.
Have you seen your more developed bird 'peck on' the other one? I find my more developed roo likes to assert himself - wanting to be the dominant one in the flock.
New line chicks at 5 weeks old. It appears with my birds that the barring is less defined. Nice, broad heads & leg feathering on the pullets.
Here's my biggest new line cockerel below.
Here are some of my old line at same age. Cockerel just below & 2 pullets in last pic.
