so i have a group of 11 birds. 1 RSL rooseter and 10 girls. full size. I have an 8 X 10 coop (TajMahal) and a huge run free range yard. question is, I know i have room for 1 or 2 full size new hens. BUT, will that equate to 4 - 6 Bantams in stead? I dont have any and am considering a few. only TSC only sells them in 6's. If i get 3 from the hatchery, (Bantam) will they be ok with my full size flock? Will my roo try to mate with them?
