I inherited these two chickens from a neighbor kid. He hatched them for a science project. He had no idea what breed they were and said they are about a week old.
I was thinking maybe Cornish X?
These are 1 week old and nearly the size of my 4 week old barred rocks.
Better photos would help a lot. I also doubt the age, as stated. If they are pullets, won't you be pleased? Folks could drop off pullet chicks here anytime. LOL
