That sounds very dedicated of you to move all the tools, etc.! She might move to somewhere more suitable – it’s still a bit early for hoglets and they tend to build birthing nests quite soon before the little ones are born. But hogs have a bit of a reputation for being a bit perverse and/or doing the unpredictable, so nothing is certain!
There also isn’t any guarantee that she is pregnant, even if you saw courtship behaviour or possibly actual mating. Pat Morris says in the book ‘Hedgehogs’: “Many females still fail to become pregnant, even after several matings, and a fair proportion may escape becoming pregnant altogether.”
Bearing in mind that, as well as how long the hogs take circling, it seems we are especially lucky to see any hoglets at all! But fingers crossed the hog there is, indeed, pregnant and you soon hear the patter of hoglet feet!
Good luck and happy hog watching!
