If size of LF Cochin chick an indication of gender?

[Mama_in_the_Dell]

These chicks are only a few days old but I noticed that one of my LF Cochins is double the size of the other. They all hatched at the same time. Anyone with experience raising Cochins find this to be a good indication for gender? The black chick is the other Cochin. The blue chick in the middle is the extra wide chick. The other two blue chicks are Ameraucanas.

Not a reliable one.

Thank you. Really hoping this one is gonna be a girl since it looks like she’s gonna be a frizzle.

He ended up being a big beautiful boy. Still growing and he’s already huge and heavy at 2 months.
