I've give a fiver a bird few months ago and just the other fortnight,,, i have 11 rollers and there's 7 of them rolling (as other 4 breeding and didn't let them out yet)anybody wants to give me 90.00 all be reasonable 2 pair you'll get will see if i can get a video up sometime Your fiver each birds could be better than them 90 a pair birds mate. Their using a well known name to sell them and there's no proof their even related to his stock. 4 of mine are 'supposed to be' masons but were nowhere near that price and I'm quite happy with their rolling ability.
