Barred rock doesn't seem to be growing

[13Bettys]

This poor little baby doesn't seem to have grown noticeably at all. They are 2 weeks old and just look at the size difference. Chicken Nugget, that's what I've named her

, eats, drinks, and plays just the the rest that I've noticed but is just getting left behind in the size department. Any ideas or suggestions?

How many do you have total?
What are the other breeds purchased and where did you purchase them from?

you might have a roo. they are slow growers .... if it starts to look alot lighter then the other's you could have a roo.

Sorry I was trying to post pics but it won't let me.
Ok I have 6 total.
2 Barred Rock
2 White Rock
2 Rhode Island Red
All are 2 weeks old today. They came from my local feed store.

Could it be a bantam?
Do you have poultry vitamins or can you get some?
