Total i have 31 chickens(now), 13 of them i have in the barn,and 18 in the tractor, the ones in tracter will not be at laying age till lat nov. When its all said and done i want to put them all in my barn. They be free ranging on 5 acres that i will alow them to roam (LOL) But i wont be free ranging them all day,just after i get home from work -till dark they will free range. My barn is 15'x20'.Is there enough room for them in there for 31 birds till i get home.
