If you want her to move straight into it, you could put it nearby and maybe move the other one after she’s moved out, if you wanted to. Normally for nesting – as opposed to naps between snacks, I would keep them further apart. But I don’t think there are any hard and fast rules. I’m sure some people keep them near to each other. You know hogs – ever unpredictable!
I have had a hog here all winter, with something in common with Cyclops – last year’s hoglet and it has no eyeshine at all from either eye and never has, as far as I know. But seems to get around like any other hedgehog and even foraged on the lawn in the middle of winter and turned from hoglet to hog. I should say did get around. The poor thing recently got a strimmer injury (nothing to do with any eye problems – I don’t think good eye sight would have made any difference at all – strimmers are really bad news for hogs) and is currently at the Wildlife Hospital – last update doing well – so fingers crossed. Probably a worse case scenario, for a hog who relies on knowing it’s habitat very well, to be forcibly absent from it for so long, but with such a horrible injury, there was really no choice. All I can do is hope for the best.
I hope Cyclops moves into the new house, wherever you decide to put it, and has a successful year – with hopefully some hoglets later on.
