I'm having the same problem, we have two young
GPs who've been on fleece for a fortnight, and suddenly today one (the hyperactive one) decided to disappear into the fleece
I didn't realise you needed to secure the fleece so well, so thanks for that
They have several hidey holes where they've been living, but nothing really cosy - I think I'll make a tent out of fleece for her to burrow in and hope there's nothing wrong to make her start doing this - seems pretty normal behaviour looking at the posts here
