Size diference between CX males and females

[Archae]

I have 4 CX supposedly. However while 2 are fat little monsters definitely roos the other 2 are smaller then the SLW and golden sexlink of the same age they also have much better feather development with nice little tails and long wings. I am beginning to wonder if the are CX. I figure they are females and I know that the females grow slower then male but that much? I would say that they are 3 times smaller then the other 2 CX. I know at the feed store they were in the same bin as the white leghorns but there was a large divider between the two breeds I am beginning to think I may have some ninja leghorns that scaled the divider.
So my question to all you meat bird people is how much of a size difference is there between the 2 genders is there? I will hopefully post pics when I get home tonight of them but right I would just like your expert opinion. I have all of my supposed CX eating 24% feed and if the little ones are leghorns I'll move them in with my other egg laying chicks and start looking up more egg recipes and less chicken recipes

About 1 lb at 7 weeks. Where did you get your chicks from?

I have nine CX that were hatched 2/14. I think I have four hens and five roos, but they're all basically the same size. Today I weighed one of each, the pullet was 2.5lbs, the roo 2.8. The difference is the roos have a larger comb, still pink, not red, but larger than the girls. I love the "ninja" leghorns--I'm guessing that's what you got! White eggs, here you come

My phone/camera is not cooperating so I will get photos as soon as possible.

Is that live weight or processed weight? I got my chicks from Cal Ranch and they were all the same size now BIG difference. I this the big CX are roos because they have pinker bigger combs.

Yup, those sound like Leghorns. Cx are just plain monsters next to standard chicks.

Well darn well were really looking forward to do several meat birds this year. Maybe now I can talk hubby into getting some turkeys now since we won't have as many chickens.

I think I been in denial for the last two weeks just hoping they were slow growers but when they started jumping out of the brooder at a week I knew that wasn't normal meat bird behavior thanks for the help.

ps anyone want a couple of leghorns?
