thanx to both for the kind welcome ,mango has seen an avian vet already and every test she had was clear..he put it down to stress an a phycological.so its a habit now we have to break her of..she was bold when i had her and she is growing some fluff back but she still takes them out if you dont watch her..we keep her busy as much as possible with toys and games.and rocky is helping to,i will take a look at the link so i can sort a pic out for you to see.thanx again for your warm welcome and help.
