Hey guys. I am new here. I have a pair of cockatiels that I house outdoors. I cover their cage at night, anyways, They had a clutch of eggs a few months ago. One baby hatched but they let it die like a day or two later. Then about a month later I believe they had a second clutch of eggs and there was a newborn too & they also let it die after a day or two. A few days later they had two newborns and they let them die too after a day or two. Same as last year, they had a clutch of eggs with only one hatched & they let it die a day or two after. Fast forward to NOW. An egg hatched yesterday & a few hours or by today the baby was dead. Right now I hear another baby bird in the nest that I believe hatched today. What am I doing wrong? This pair of cockatiels that I have are new parents, I'm thinking they don't have experience in feeding or being parents. Are they not keeping the newborns warm and or are they not feeding the newborns? the nest that I have is a 12"x12" box with wood chips in it. What should I do? I am told not to disturb the parents or the newborns and I should avoid looking in the nest, if that's the case how am I going to know if the parents are going to feed the newborns. It's not like if I am looking in there constantly throughout the day. I just check on it maybe once a day. I do not have an incubator or I don't know how to hand-feed newborn cockatiels. Any advice that you guys can give me? I hope they don't let this new one die. I've been trying for the last 3 years to breed cockatiels without any luck. Thanks
