Both of them had the barred look on their feathers - making me wonder if they had a bit of Barred Plymouth Rock in them. Below are some purebred Plymouth Rocks - the paler one is the male and the darker is the female. Pure males have 2 of the barring gene and thus end up with lighter bars.
However, I noticed that there might be a bit of Araucana mixed in for Cacciatore and maybe for Bubbles too! Here is Bubbles - look at her comb.
She doesn't have a comb like the other two, it seems to be just a bit knobbly. Apparently, the breeds that have pea combs include Araucanas and Brahmas. And it seems to me she only has one row as opposed to 3 rows. A single row indicates a female, three rows a male. Look at these pictures of female and male pea combs:
But females can have a red comb at a young age too, like this one:
Araucanas can have beards and a fluffy head. Here is a lavendar Araucana female:
And if you look at Cacciatore, she has that funny feathering on her head too! So perhaps there is some Araucana genes in there, since the 3 original chicks are from the same batch.
