I have a red and a bantam. The bantam was supposed to be a sexed pullet, but after doing some research into the characteristics of a roo, I'm thinking my mini-she is a mini-he. Also, I think my RRR is a roo. The bantam is kind of a bully, but the RRR is very shy and reserved. They're both 8 weeks tomorrow. I know I have at least one roo because I've been hearing the start of a crow every morning.
Here's both that I suspect are roo's.
Here are my two RRR's together for comparison. The one in the back I think is definitely a hen. The one in the front is my suspected roo.
Here's a few of my bantam, Petrie.
