Could this be an Exchequer Leghorn? She didn't start laying until 10 months old. It's a small white egg. I got her from Cackle Hatchery in a hatchery surprise package. Her comb seems to be getting a little bigger. Does it take a while for Leghorns to get the large combs that lay over? I've only gotten a couple of eggs so far so I don't know how often she lays yet. What do you guys think?
