Fertility from last year?

[steve56616]

I put a large box filled with sand and top soil on the hottest part of the garden. Steps leading up to it and plants all around so she doesn't feel too exposed. Today I showed her it and she seemed to like it and spent a while sniffing and a bit of digging then started eating overhanging leaves, then walked off and went into her house
She has only been here a few days but seems to know the layout of the garden already.
She is eating loads so I assume that's a sign that she isn't ready?
