Slow to grow

[3 barred rocks]

My blue cochin is slow to grow. She is much smaller then the other girls
her age. Is this normal?

Are the other birds different breeds and, if so, what breeds are they? How old are the birds? Are you certain that she is not a bantam? What are you feeding? Do you have more than one feed/water station available so that she can't be kept from having access to food/water by anyone higher in the pecking order than she is?
Perhaps you can post a photo of her and her flockmates so we can see the difference in sizes?

I have 2 White Leghorns, 2 Jersey Giants, 2 Barred rocks, and one full grown barred rock, all hens.
She is eating well and pushes her way in the get to the food

X2 on that. Without a picture, it's like shooting in the dark to give you an answer.

I did contact the farm i got her at, she is a bantam..i guess that explains it all!
When I can get a pic i will post. We named her Eore, from Winnie the Pooh.
Thanks everyone for your advice and comments
