Thanks for the replies guys, i should also say that to see the bird on the floor feeding etc she looks mint but just cant get to the box. She has no swollen joints and handles not too bad just a little down but i put this down to laying. I will isolate her for a few days and see what happens from there, she is too good to cull just now but if no improvements are made she will go, i have already made my mind up on that.
