Hi Sarah
If the hog is planning on giving birth, you’ll have to wait to make any alterations until later. Presumably there is a comparatively large door which the air can get in through, although I would have been happier if it wasn’t covered in plastic – which might be more likely to lead to condensation. (although maybe you only mean the top). Hopefully in the shady part of the garden there won’t be so much difference in temperature to cause condensation which might be more likely in the winter.
The main thing is that the hedgehog has chosen it, as it is, and we have to trust in the wisdom of hedgehogs to choose something suitable for it.
Brilliant news that it sounds as if it’s building a nest. Fingers crossed for a litter of hoglets wandering round your garden later on. Let us know if you see any out and about.
Good luck and happy hog watching!
