Since you do carpentry by trade, see if you can save up from your jobs that could be used to alter the coop. Doesn't have to cost you money if you can use unwanted/excess material.To clarify, that coop is not their life. They have a 24x36ft extended run that they get let out into every day after work and pretty much all day on Saturdays and Sundays.
We're not really in a position to buy more stuff so we're working with what we have.
I get the whole covering up the run of the coop idea, and thats certainly an option. But I'm a carpenter/lumber mill worker/woodworking hobbyist by trade and I wouldn't want it looking crappy, for lack of better terms. I'd have to give that idea some thought on how to go about it.
You'll probably find they do need to be out more than just "after work" unless your hours aren't typical. While they're younger and smaller they'll tolerate tighter confinement, but as they mature and grow and hormones start going, they may not remain so tolerant of one another.
