You’re doing a great job!
I hope you get all the kinks worked out!
Are you going to build a separate pen for your other broody?
Whatever you do, DON’T MIX THEM!!!
This year, I had 3 broodies all at once… since I didn’t have another option, I put them all in one pen. 2 of them were constantly fighting, and gaining up on the other sweet one…. They even killed one of her little fluffy sweethearts.

I ended up having to build a whole bunch of hap-hazard fences to separate them for the next 6 weeks.
I don’t know how yours are, but mine were a mess!
