I think my barred rock is a cockerel. I will try to get a pick posted tomorrow.
The store I got the chicks from had about 15 different types of chicks. On the list of what they ordered that could be white were leghorns, cornish x, red stars (the cockerels would be white), and that was it. They had barred rock pullets but no white rocks. However, they had signs saying what were in the brooders and there were more breeds on the signs than they had on the hatchery list. For example, they had a half dozen or so Buff Orpingtons but no record anywhere that they were selling them in the store. It was very confusing. I told the store that I didn't want any white chickens since they are going to be free range and I'm worried about a predator getting them. They looked at me like I was evil. Oh well...I love the chicks all just the same and will do my best to protect them. I have not been back to that store since I got the chicks.
Today I weighed all the chicks. They are 5 weeks old. The smallest one is the Welsummer and she is .6 pounds. The largest one is 1.6 pounds (she is gigantic) and looks like a RIR. The white ones are both around 1 pound so I doubt they could be Cornish Xs.
These are BABY cornish X...they are about 2 weeks past delivery from the hatchery, and from here you really cannot see their insanely heavy shanks and broad stance.
If you have never raised meat birds, then you will never understand what they are all about.
They are sparsley fledged, and grow with insanely fast growth, their shanks are heavy, heavier than any other breed.
In 2 weeks they will be DOUBLE the size of other breed chicks their same age.
By 1 month, the cornish X will be 3 X the size & weight on the other chicks their own age, and it goes on,
