Wood chips for bedding?

No, just in the front. The ceiling is the only thing (besides the rafters) between the hens and anything that might try and get in through the roof. Also, I don't want the hens roosting on the rafters because there are nails sticking out of the wood. I doubt they would, but the ceiling is working as a extra precaution.

Well, that's why you'd put 1/2" hardware cloth over the open soffits.
And you can put chicken wire on the bottoms of rafters to keep the birds from roosting there.
