First of all sorry if I didnt put this in the right section. I am in the planning stages for chickens for next year. Right now, if I have figured it right, I need at least a 4x6 coop for 6 chickens. I plan on letting them free range during the day my yard is fenced in with a 4 foot high chain link fence is that going to be high enough to keep the chickens in the yard? Oh I am planning on getting Ameracaunas and maybe buff operingtons or wyandottes.
