Can anyone please advise me if there is any problem mixing EY and AY gouldians in a large Avery.

Yes... try to keep those mutations separated for the betterment of the bird...

I agree with VP, keep different mutations separate as their off spring will just destroy what breeders have been breeding for many years as for want for a better word "pure" and not a cocktail of many mutations that we could end up with.
The mode of inheritance is different as well, EY is sexlinked dominant recessive and the AY is autosomal recessive.

What has been the effect of this mixing of mutations. Does it lower fertility of yellows or cause early death etc?

It has only one nevative effect. The big one. Impurity of type. The birds are just as fertile as any other, and just as long lived. Mum has a mixed yellow cock who at 5yrs old has his most successfull year, but his chicks are everything all mixed up. They will be sold to people who just want backyard colour and are told what they are getting, or kept for her own pretty backyard stock.
