Hello all. I'm new to chickens and am weighing all my options for a coop. My son brought home some chicks from his pre-k class (small rural school) and I've got them in a brooder box at the moment so I have five or six weeks to get everything settled, but searching through these forums and looking at pictures has given me just as many new questions as it has answered. I have three and a half acres of land, south of Tuttle, OK. The only fencing is barbed wire. I have an empty 8x10 storage shed just sitting there waiting to be turned into a coop. From reading up, I know I need to make sure it is well ventilated without being drafty, I need to build a roost, some nesting boxes, and cut a door in the side for exit/entrance. All of this seems well within my abilities. What I'm unsure of is the actual need for a run. My wife and I plan on letting the chickens just roam the yard at their leisure as her mom has a yard full of chickens and guineas that pretty much do the same. Our land sits in the middle of pasture so neighbors wouldn't be an issue. My wife works from home and there will always be someone here in the morning to let them out of the coop, someone here in the evenings to put them up, and everything else that is required for their care. Given all of this, is it anyone's opinion that a run is actually necessary? I understand some chickens may wander. I understand the predatory issue...we do have lots of coyotes around here, but am unsure if I should be worried about coyotes during the day. The chickens would be in the coop at night. I'm really just needing some opinions and advice. Also, I forgot to mention, we don't plan on having more than 5 chickens or so, mainly for eggs and for my kids to learn the value of raising animals. We also don't plan on having a rooster but if this were to accidentally be the case, it'd be ok. Thanks for any help.
