Well Peach seems to be settling in great. Had her just over a week now, and she is quite friendly, still rather jumpy but lets me stroke her on the head, and under her chin. She'll come over to me when I go near the cage. She also loves playing out (Has her favorite spot to sit on my sons chair under the table. She's very easy to get back in her cage, she has her bath, and then has a raisin and goes back in. She also jumps on my knee whilst I'm sat on the sofa.
My other half purchased a flying saucer wheel for her today which she loves. She runs around on that thing for ages, didn't take her long to get the jist of it at all.
