My husband scored two of these boxes from work - they were going to throw them out. One I will be using as an interim brooder (grow out pen). I don't know what to do with the other. I am in need of isolation pens and breeding pens. How would you turn this into one of those two things? Inside dimensions: 78 in. long, 42 in. wide, 26 in. deep. This one has two partitions, which can be removed, as you can see one has been.
