Ok, got it now. Sorry, I just wasn't sure what Smom was asking. I've never heard of a rooster touch test, and actually, I didn't know hens would squat when petting when they reach laying age.
And BSL must be black sex link.
I'm sorry, but I don't understand what you're asking. Are you trying to figure out which hens have started laying? What's a rooster touch test, and what does it have to do with laying? What's a BSL?
