Thank you!
I'm raising my RRs like regular layers on typical chick feed so hopefully I can get some females to lay age. I've heard the roos can be snotheads, but have no experience nor do I have plans to try AI. The experiment is just for feeding my family so will leave them take care of things on their own. If my layer flock has some broodies I'll put eggs under them, and if not I have a bator.
Hopefully I can try a variety of crossings within the meatier bird pen and keep the layers out of it in their own pen. So, I don't need to be worried about dwarfing genes or undesirable health issues crossing RRs? (aside from the typical things)
