Issues: 1. Need a place for babies to grow out 2. Need a place to have roosters live in, either permanently, or on a rotational basis. Further, if roosters fight alot, this may require even more housing........ 3. Need a main laying house...........Should this ideally be separate from the 'breeding stock' house? (For example, you have all your layers in the layer house and you 'get rid of these' every year or two to keep production going. THEN you have the house for the breeding stock. It is from these breeding birds that you create new layers, which then go into the laying house. The breeders you keep for a pretty long time, UNLIKE the layers which are switched out regularly............) 4. Need an extra coop large enough to stash your WHOLE FLOCK when you are cleaning their coop(s). I am assuming that a good clean may often take a couple days: dry the place out after washing, etc............ 5. Need a place to quarantine an injured or sick bird............... I have one 8' x 8' coop (walk in) two 4 x 8 coops (walk in) None of these are used regularly, though I have stashed my roo in one of the 4x8 at times, to give the girls a rest, The main laying house is 10 x 16. All the birds live in this. There is often a roo with them, though not always. My run for the birds is about 6,904 square ft. So.............another of jmc's impossible questions!
