I'm Becky, totally new to chickens. Started out intending to order 2 buff orpingtons, wound up with 7 chickens...oops. I have 2 buff orpingtons, 3 splash silkies and 2 stowaways. They were supposed to be lavender orpingtons but I just discovered they are instead lavender ameraucanas. Any chance anyone can help me determine whether the stowaways are pullets? I originally ordered pullets but consider and I got the wrong chickens, I'm a little nervous that they might not be pullets
