I've found that Bourkes are more aggressive in the nest than budgies. If you have Exact and want to take him out to hand feed, it's probably not too late. Once he depends on you for food, he will begin to trust you.
Good luck with him. Being a lone nestling is going to make him more easily frightened too. There's safety in numbers. Smile.
By the way, I usually only clean the nest boxes between clutches. It's not necessary to do it more often than that--especially with only one baby. The only time I've ever cleaned a nest box while it still held babies was on a hot summer day when a box with five older babies began to emit an odor. If it's not hot, and the birds are few, the pine shavings usually absorb and control odor. Disturbing a mother can be risky to her offspring if she's not tame.
You haven't said where you are. In Australia I've read that wild Bourkes begin breeding in November. In the wild nearly all birds begin their breeding activity in the spring, during warmer weather, and carry into summer. Depending whether you are in the northern or southern hemisphere, which month they begin is going to be different.
My husband found this book for me many years ago on Half.com. It was mailed to us from the UK. I've seen a few others occasionally on the internet, if you're interested. There are a few things the author and I don't agree on, but for the most part it is informative and she makes some worthwhile observations.
I really do not understand why the chicks died. There are two other pairs of bourkes in the aviary and I did not see any signs of them going into the nest box and causing any issues. Have you had this experience? One person told me it might be due to the lack of humidity causing the shells to be too hard. The aviary is outside and I do not think this is the problem. Another person told me the hen might have been spooked off the nest in the middle of the night and the eggs got too cold. It would be nice to know what happened and try to prevent it from occurring again. Thank you.
It's always heartbreaking when eggs don't hatch, but it's happened to all of us. This year my oldest hen laid four eggs and hatched all four. The first two had red eyes, but both died...one the day after it hatched and the other a week later. She managed to raise the other two with dark eyes.
Better luck next time. Bourkes typically go right back to have another clutch. Make sure you have plenty of fresh water available that she can bathe in. If needed they carry moisture into the nest on their feathers.
Hi! I just purchased a beautiful more coral colored than pink) rosey bourke and would like to know if u can please tell me how to get a close bond with him and how to bathe him. Any insight would be wonderful. I need all the help I can get. What should I be doing with him to make him want to be with me and trust me?
When you feed make sure all the air in the eyedropper (if that's what you're using) is out of it. It means expressing some of the food until it's all at the tip. Also, I make more food then I'll use so that I can put the tip of the eyedropper down into the food and not pull any air into it. I refill before all the food is out of the eyedropper.
Good luck. You'll have some very sweet birds!
I have a quick question for you regarding my four hatchlings. Their nest box is really dirty, is that normal or should I clean it and put fresh shavings in it for them?
If the babies are still in the nest, I don't remove a box to clean it. I do remove the babies to a safe, dry place...into another box deep enough that they can't escape. If they're feathered, put the box inside a cage or close the box's top because they can fly away.
