I got my chickens this past Saturday. I found a couple Buckeye pullets and my friend's father-in-law gave me two. Well, on Sunday morning I was trying to get into the coop (it's an A-frame) and was being careful to not open it too much, just enough to do what I needed to do and one of the chickens decided to fly the coop. she ran thru the neighbor's yard and down the alley! I followed but lost sight of her and looked all day long off/on and could not find her. Any ideas what to do?
