Parrot toys - good point. I always avoid the ones with aluminum and pigskin.
I'll amend that later today or tomorrow.
I'll also read through the cages and toys pages again and see where I can amend bits.
Dust bath dust
is known as sepiolite here, and comes in 2 consistencies - the usual dust bath dust which is like very fine sand (very small grains and not really course) and the finer dust which has a consistency a bit like flour.
On the colours page, in the NCS shows they have in the UK they do break the groups up a bit more, e.g. there could be a class of wilson whites and a seperate class of pink whites. All of the colours I have named have been recognised and named in the shows I have been to, except a tan would be known as a "self brown" (there, I've spotted something else to add to!). I could add a point about what the MCBA say too.
Thanks for your comments so far.
