@Liz Field
the coop they sleep in accommodates 6 hens,
I don't know your experience level or what you are basing this "6 hens" on, but many prefab coop manufacturers typically claim it can hold 2 to 3 times as many chickens as we would normally put in it.
I don't hold a lot of hope of this...
I'm glad you asked before you just got more. You might follow the link in my signature below, it explains why I don't believe in magic numbers for chickens. We keep them in so many different ways that no one number can fit us all. There is another part of it too. I find the more I crowd them...
