I don't know, Bots. I am going to wait to see what happens with her tailfeathers- once they grow, I'll see how she goes. My hubby suggested tying a bit of string to her leg and letting her out to flap about a bit, so she can flex her wings- but I've been waiting for a few weeks, hoping the wing will heal because when I brought her home, she flapped around and it caused her to bleed from the injury. She's been fairly quiet now for those few weeks but starting to run up and down her ramp and flapping a bit without any repercussions (that I can see, anyway). I think she will be a loner, if I do release her here- and this would be a great place to let her go- but magpies are quite territorial so she would be hounded away from here as soon as I let her out, although she'll probably find somewhere nearby to call 'home'. But what will happen when we move and she can't come back to be fed?
I guess I could try and see if my next door neighbour will have her- she has birds and might have room if the magpie needs a cage. And I know that my neighbour will feed her. We're moving to a place that is right on a fairly busy road, so not suitable for a young magpie.
