Ok so my daughter has designed our chicken breed coop/barn. She is serious about her chickens!! It is 30'x42' and has 12 different coop/runs. There will be a 12x12 storage/incubating room. The runs will be 6x8 and the coops will be 4x6. One of the pens will be for young roosters and another for grow out chicks. Now, She will be getting orpingtons(Buff, lavender &silver laced) and I know they are quite big so my question is how many per 6x8 would be a good number? And is 6x8 a good size for a run? Each day 1 breed will be let out to freerange on rotaion. Also would linoleum be a good choice to put down in the coops for easy clean up?! The chickens we already have: Golden lace polish (4) Silver lace polish (3) Silver laced cochin (6) Golden lace cochin (1) And our meat/egg birds (rir & red sexlinks) Thanks for any input!
