Hey there
Aspen Anderson I hear ya and I sympathize!

I have bantam Cochins who spend more time broody than they do actually laying eggs
Anywho, I did just want to say, being a first time mum, if you give her chicks, watch her very closely as there is no guarantee that she will accept them and may attack them. Also, giving her chicks means that you will either have to separate her from her friend anyways or take the chance that the friend accepts them also.
I do not want to be an alarmist but just want to advise that you have a Plan B [brooder] ready if Plan A does not work.
Good luck!
Oh and I also wanted to say, there is no reason that your broody can not have company in broody jail so, if you make the broody jail big enough, she could take a friend
