It's about the same as yours. Remember how my run is made from cattle panels? That means I have the framework of cattle panel fencing arched above it. So what I do is just hang (using zip ties) some of that green plastic fencing all the way around it. At the place where I can walk in, it's just held to the side with a bungee cord. Would some photos help? Pretty dusty out there at the moment, so if you can overlook the dust I'll try to get a couple.
Don't you DARE apologize for posting such a question here! If we can help, that's what we're here for, and your questions are no less important just because you aren't using MHP yet! Sounds to me like the little one does need some heat, but also sounds to me like she's found just what she needs to be comfy and her provider isn't objecting in the least. So it's your call, but I think I would.
Honestly, this is the best BYC group that I've interacted with! Everyone is incredibly helpful and encouraging!
