Being new to chickens (yes I'm hooked already) I would appreciate some advice. I have a portable greenhouse that I only used for gardening, no longer gardening now that the chickens went in the garden space. I was thinking of using it as the frame work to add on to the small coop, as the roosting area. Frame is 56" x 56". Use plywood on the sides(put in an access door for cleaning), on top use corrugated roof panels. Or would doing an all wood addit in be best? Pictures of what I have. I know the coop is too small for roosting, be more of a big nesting box. Have 3 rescue chickens (brahma, Plymouth rock, and EE). Knew the coop would be temporary.
