They are about 18 weeks old, they are my neighbor's and he is wondering what breed they are, he got them at a feed store and they were white as chicks. I am pretty sure that they are all hens, since none of them are crowing and I don't see any hackle or tail feathers. They have thick yellow legs and short beaks like a cornish, pretty friendly, red earlobes and they are not laying yet. Thank you! ETA: they have red, black, and barred markings, I was thinking a Delaware/White rock mix, whatcha think?
