So my husband refuses to buy a new coop .. so we behave to use one from our older home we brought with us we will be using this coop to house 7 chickens (too small I know!) was they will have 100 square foot outside of this coop as well I’m wanting to try to convert the “run” portion of the coop to just a coop adding more roosting bars on the bottom and using the nesting area for.. well.. nesting.. my plan at first was to use plywood and fit it into the gaps where the chicken wire is but the dimensions are odd and we don’t have experience Cutting odd sizes properly. My next idea was (ugly ) but white corrugated plastic... id rather not. I came across this photo of a cover over chicken wire .. does anyone know what this is.OR have any better (and not to expensive) ideas other than building /buying a new coop)? Thanks guys
