I’m a little confused, do you own the parents or just the babies?
I’ve handfed all my birds, but never lorikeets. I do have two lorikeets however and they are very aggressive birds, even to each other.
I’m not sureI can help with any handrearing at all, as I’m pretty sure it would be different than a normal parrot.
I’ve handfed easily over 30 birds and I myself would not do it. I would have really suggested you get a weaned lorikeet if that’s what you were after.
Speak to the person you obtained them from-if they have been breeding them they should know what works vs what doesn’t. Handfeeding without experience is dangerous. In the beginning I did have a bird die from it- a lot can go wrong.
As for the mixture of nectar I use 4 tablespoons mix to 1 cup of water. That is Blessings brand which can be found at mysafebirdstore.com. I can’t recommend mixture amounts for other brands.
When they do start eating on their own-avoid all citris, grapes, bananas, seeds amd hard foods.
I stick to a very short list of foods that can be had daily- peaches, pear, apple, watermelon, cucumber. You want low iron and these fruits are the safest. You can blend them or finely chop-watermelon can obviously be offered just sliced.
Nectar should be changed twice a day, do not leave in the cage at night. I find it keeps longer if you offer it cold.
Your babies should be pooping, or should I say squirting (yup, ew!) regularly. Which means A LOT. Always offer fresh water as well. I also give mine a dry insectivore/softbill mix that they just love, also made by Blessings. It’s called Bugs n Fruit.
Lorikeets are hard to handle but once you’re down to a routine and your safe list of foods it becomes easier.
Good luck
