Are there any issues I need to deal with to use my working greenhouse as a "coop" for some new chicks I will be getting this fall. I am new to raising chickens so any help would be appreciated. How high can the humidity be without being harmful? I keep the temp in the greenhouse about 45-50 F at night. Daytime temps depend on sunshine - which can be lacking in the Ohio Valley in winter. Do I need lights? Do I need nesting boxes and roosts? There are tables (4X8 with hog fencing wire) that they can roost on. I was planning on making nesting boxes anyway. Thanks ahead of time for the info.
