You need to check the nest box everyday to make sure their getting fed. If she isn't staying in the box with them then you may have a problem. But in any case you need to look at their crop, it's about where their chest would be. That should be puffed up if their being fed. Normally birds don't eat at night so it's strange to hear them chirping then unless she hasn't been feeding them right. Look in the nest box now and make sure their still alive. If you need to you can hand feed them. Look on youtube to see how to do this. I raise birds and I hope this helps.

The baby budgies i have bred have never really made much nosie except when mum feeds them. The mum will not leave them the first few weeks and the male feeds her enough for her needs and so she can fed the babies. Once the babies are old enough that they don't need brooding all the time she willl start spending more and time away from them and then both parents will start feeding them. At night when dark they will be quiet as the parents don't fed them.

Okay so its been 12 days since the first baby budgie hatched through these 12 days ive been hearing them chirp all day and all night ..but these two past days i havnt heaerd them that much at night ... i was just wondering if budgies stop chirping so much as they grow... or if they chirp when theyre getting fed... i really dont want to look to much in the nestbox so i dont disturb her..is that okay?
