I am new to this site and new to the idea of having some chickens. This is one of the most helpful, friendly sites I've been to. I have read up to 50 pages from each discussion area, most recently reading the emergency/illness stuff... I am thinking about getting some of my own hens after buying fresh eggs here in town, then having them run out for short periods. I have a compromised immune system - Epstein-Barr and other autoimmune diseases that commonly appear with E-B. I was going to put in a greenhouse last year, but ended up not doing so because I don't breathe well in damp conditions and can no longer tolerate very much sun at all. Do you think I can raise up to 3 layers w/o affecting my health? thank you! D.
