With thanks to those who offered suggestions on "taming" Argyle, particularly Chris (ecodweeb) who gave lots of helpful advice, I thought I'd offer the latest on him.
Well it's been about two weeks since I asked for advice and in that two weeks there have been positives. Argyle does seem to be warming to Jordan & Steve, he will allow Steve (not always but more often these days) to stroke his beak and feet through the cage bars, he will welcome Jordan home from school with a "hello", he also says this when Jordan answers the phone lol and he will dance with and for Jordan, HOWEVER it does seem to be me he dislikes intensely. It is rare he will allow me near his feet and even rarer I'm allowed near his beak!
I was wondering if his behaviour might have been hormonal and that this could be the reason it has got a little better.
TBH I'm beginning to get a little paranoid, why is it always me my fids reject? Steve seems to be the chosen one for both of my guys even though I am the one who feeds and cleans them.
