I've seen similar posts about merging flocks but does it matter with size? I have 10 large fowl and 3 bantams (1 silkie and2 frizzles). They have lived side by side in the coop and run partitioned by chicken wire for almost 2 years. We recently moved and I was able to recreate the separation of coop and run within the same space in an existing shed. Since we moved in the winter with no chance to build suitable quarters it is small. My hubby is letting me take over an unused pole barn that I plan to turn into a proper coop. I plan to use a portion of two of the bays and the dimensions will be 19x10 for the coop with additional storage and while I haven’t decided the footprint for the run it will be considerable. Rather than split this into two coops…I was wondering if I got more chickens this go around, because it’s spring and well…you know, chicken math, …let’s say maybe 7 or so depending on cuteness…. Do you think I would have any problem putting the new ones in along with the bantams together with the existing 10 or will there be issue with the little girls? Yes, I know I would have to let the new arrivals feather out first but when they are ready I was wondering if I could slip the banties in with the newbies. Your thoughts are appreciated.
