Hi Rosemary,
OK, your pair is just now barely old enough for breeding. So right now they are practicing more than anything. Even if they produce eggs, I wouldn’t expect too much. First clutches almost always fail because the parents are learning. I’m concerned about the diet because they do not drink enough water for vitamins to be very beneficial. If they are eating pellets, then they get what they need from the pellets. If they are eating loose seed, then you need to stop trying to breed them until you can get them converted to a good diet. The hen especially needs the best nutrition because forming and laying eggs takes so much out of her. I would continue to offer veggies daily, because breeding birds tend to eat foods they wouldn’t eat before once they have eggs or chicks. I would highly recommend that you try to find some Galah breeders who will give you some advice on breeding this species. Cockatoos are notoriously hard to breed, and male cockatoos have the tendency to attack and kill their mate. With some species, the pairs have to be separated outside of breeding season. All I can offer is general advice on providing a premium diet, the right caging and nest box and privacy. It’s very important that you seek species specific advice from some Galah breeders, so that you have a better chance of success and avoid any tragedies such as mate attacks.
Thanks for the update!
