My cockatiels have..."done the deed" many times since Lucy flew away (thanks a lot dad) and they're gonna be parents soon. Of course ill be getting a new cage for the 2 babies I will be keeping, (I didn't even want two more parrots, I just wanted to keep Lucy, thanks again DAD.) and will be selling the other ones, to people who will be good owners ofc. So, id just like some tips for being a future grandma. What should I use to make the nest? Do I need to know anything about cockatiels and their babies? Like do cockatiels reject most babies? Will I have to hand feed some? Basically, give me some good tips. Thanks.
