Thank you so much for all of this!
I am giving her calcium so that is good. With the flock, I can just keep her in the run and leave the others out, thanks for the tip. I’ve been watching them and they aren’t going near her so I assumed it was ok but you’re right, best to keep them apart.
And the flies- it’s super hot here so I will try to keep them off. Flies are everywhere this time of year (even in our house as we live on a small farm in Southern Europe) so I will do my best!
Thank you again for all of your help! I will keep you posted!
