I'm not sure to be honest. I've got these five for this year and wasn't going to hatch anything out from them any time soon. I've got some EE pullets coming in the mail about March 15th and was going to hold 5 more back from that to add to them. I just like to be able to free range all my orps...
I can do the giant cochins if and when they ever start to lay <sigh> but the EE's... well, I only have girls and they are running with the buff orps. I got them only for 'pretty dozens' for egg sales. So they'd be mixed.
But if that sounds good to you.. it sounds good to me!
