Hi, I should of given a update. Yes she is fine, her wound has completely healed and the feathers are back, she's laying and everything! What I did with her was fed her scrambled egg every other day for a week, due to work I only fed her in the evening and she prob didn't even eat as much as a teaspoon full. I also got one of those syringes from sainsburys chemist and put in some olive oil and fired that down her throat (it was hard to do it slowly). And then because the egg feeding took a longggg time I switched to yoghurt for the second week of hand feeding using the syringe again. Then left it up to her to live or die and luckily she lived!!! Oh I also put water in the syringe after feeding to give her a drink. The whole time she was in the house in a dog cage. When I put her back out she still didn't seem 100% but I think she was actually a bit depressed because she perked up a lot once she got outside. At one point I did think she might of had impacted crop so I massaged her crop everyday but I'm still not sure if she ever did. I think the throwing around of her neck was due to stress of the fox attack and prob me feeding her and not impacted crop.
Sorry I've really waffled on but I just want you to know everything I did and seemed to work. Please keep me posted on how you get on and good luck!
