I'm going to need a chicken coop for my two bantams that are three months old. I want a coop plan that is good in the winter and summer, I want to be able to come in the chicken run and pick them up and not have to crouch down (I want it to at least be four to five feet tall, I want one that be easily built, and can fit at least 6 bantams comfortably (just in case I want more). Please help me my chickens are way to old to still be a tiny little pen and not a coop. Thanks!!!!!
