Hi everybody! I have 4 chickens -- 2 EEs, 1 cochin, and 1 speckled sussex. They have a 4x5 coop and an 4x8 completely enclosed run, which they have access to during the day. The layout of my yard is such that the chicken setup is tucked into a section where 3 sides are enclosed by a privacy fence and the fourth side is open. Long story short, I enclosed the fourth side of this space with chicken wire about a foot and a half tall so I can let the chickens out into this piece of the yard relatively worry-free while I'm home. This worked great until 3 of the chickens discovered they can fly out into the rest of the yard (poor cochin, she always gets left behind). So my question is - how tall should I make this section of fence to discourage the chickens from flying out? Has anybody else had a similar problem?
