Hi Finchy,maybe this will help you,I have an aviary built onto the side of the cottage containing Zebras, Java Sparrows, Bengalese Finches, Diamond Doves, and two Cockatiels. Now the mortar in the stonework is made up of the old fashion mix of cement, blackrock sand, and a measure of the ash left over from fires. Whilst I always give them crushed oyster shell and grit supplement, those little things have nibbled a fair amount of mortar out of the joints. I have had no problems with the birds health and there has been no problem with any of the egg shells or chicks that have hatched. So i think that even if you didnt give them any they will manage quite alright without it, but its nice to know you are thinking of them.
Take care
