I am facing real problems with one of my favorite cockatiel breeding pair. Their chicks readily die after 2 or 3 days but with the same diet other chicks survived. I m offering soft food daily which is mixture of wheat grain, corns, peas, soya beans along with seed mix. Also boiled egg chopped with 2 slices of bread in a week. Its 2nd time their chicks died despite proper feeding by parents. I don't know what to do. In previous season they grown their babies but now babies died in both clutches.
