Due to the fact that I'm on a city lot where poultry is verboten, my 5 chooks live in a 70 square foot coop in my single car garage (along with Cayuga ducks at the moment, but that's another story). I've just brought home 15 coturnix who are currently housed in a giant stock trough in the aforementioned garage. My questions are these: 1. Is being exposed to dust from the chickens a serious health risk for them (e.g. will they keel over from Blackhead)? 2. Which foods will keep them healthy with good natural immunity? 3. Where does the balance between these two factors lie or should I just move them to the basement? Thanks in advance!
