Hi Sweetleaf
I pulled my babies from their nest at three weeks. I have been given excellent advice from fellow site members namely Molossus and Lushen. Lushen is breeding IRN's for a second year now, but Molossus is an old hand at breeding parrots. It is Molossus who has helped me find my way as a novice breeder. He told me that it is best for a novice to remove babies only after 3 weeks, as the babies would be stronger (getting the neccessary antibodies from being fed by their mum IRN) and at this age, they are easier to handle.
I also use a scale to weigh them before and after a feed to ensure I am not over or under feeding them.
Lushen has posted pictures of his IRN babies daily, giving us novice breeders a chance to learn how they grow and how best to take care of them. It is fantastic....check it out under 'My Pairings for the 2012 Season' by Lushen. Fantastic!
I do not have a brooder. I live in Durban, South Africa, where it is fairly warm (even through Winter). I guess if I removed the babies at birth, I would definitely require the use of a brooder. But it is better leaving the babies with their mum for a while, so they get the necessary nutrients and antibodies. But it has been an absolutely delightful experience so far...really enjoying the ride!
Kind Regards
