My cockatiels had babies,which are now about 6 weeks old. The parents have recently been breeding all the time again & we got back today to find an egg on the bottom,what do I do? They already have 3 6 week old babies & I'm worried. The babies have fledged the nest so I took the box out yesterday & the older 2 are starting to eat for theirselves but all three still get fed by their parents. What do I do?
