I'm just wondering if I should build another coop for my younger birds this winter. There is enough room in our current coop and run but some of my hens can be kinda mean. I have them in a smaller crate inside the coop now just so they get used to the newbies but it kinda freaks me out to mix them. How many of you mix your bigger birds with younger/smaller ones? I know they have to work out an pecking order but I don't want anyone to get hurt... Thank you!
