How old are they silkies you can’t really sex until they lay an egg or get on someone’s back the blue my guess is a hen and the red looked to be a roo

Very cute birds. The second white one looks like a cockerel. The others are too young yet.

Thank you all. They vary in age from 10 weeks to 6 weeks. I’ll be sending new and better pics in a few weeks. One of my 6 week old has sour crop. I’ve read up on it and treating her for it. I’m praying for her.
