Thanks for your thoughts. I've been thinking roos for a couple of weeks now. I'm thinking I ended up with 5 or 6 roos out of the ten we got on straight run. Now we also have 21 others that were purchased as pullets. So far, no surprises there. I guess we'll see.
I'd say the BOs are definitely boys. My month old pullet's comb isn't pink at all, and you can't see wattles at all.
And the RIR pullet I have is more feathered than yours and her comb is smaller.
