a small dog crate would work. As long as it has room for him and food and movement until you can get something bigger. Or section off a corner of the coop.Thank you for such a quick response. Ugh. You're right. An additional pen will take some time to build. What should I do in the meantime? I don't want to get rid of him, but I fear I should.

Ah, thank you. I'll try it. Thank you for the encouragement.
