this is one example of chewing (all three are babies)


What is your opining of the material they chew?

It looks like wood with some kind of veneer on it.

Is it bad and dangerous to chew?

I today tried to look closely at the chicks. The problem with the nestbox being inside the cage is that I basically have to insert my head into the cage to see better. Then I have to be in an awkward position trying to reach for the chicks. Plus I am scared to hurt delicate creatures. Anyway, some of them have really full crop and some I couldn't see. One chick was buried under the siblings, and wasn't easy to get. I do hope that parents feed all of them. I will try to do more checking tomorrow.
Do you know, when they feed, do they only have available what they ate, or can they draw some nutrients/resources from the body even if there is no more food they ate? I think if breast feeding woman didn't eat today, her body still would produce milk to feed the child. If there is no gas in the tank, the car won't drive. Which situation are birds similar to?

Ouch! Those poor windows.

You could try getting some waxed paper (in the supermarket, by the bags and wraps section).
Cut a piece about 4 inches wide and the length of the window. Fold it in half. Tape (or tack) the bottom half to the window with the fold toward the glass.The top half of the wax paper is free. This may discourage the birds from landing there.

It also helps to find something else they love to chew for them to choose as a substitute.

Mammals create milk out of other foods they have eaten. But as far as I know cockatiels rely on the food they have eaten to feed their babies and don't create something new out of their bodies to give them. So if the parents don't have food to eat the babies won't be able to eat either. But the parents can store food in their crops for a while, and this is what they use to feed tiny babies in the middle of the night.

It's normal for the youngest chick to be completely buried under a pile of its siblings in the beginning. The parents will normally manage to feed it, although I'm not sure how they do it. Squeebis was the youngest of six chicks, and his egg was so buried beneath his siblings that I wasn't sure he would be able to hatch. But he did, and he was also fed regularly even though I couldn't see him at all most of the time.

I think the chicks are doing pretty well. I don't know if 3 remaining eggs going to hatch, probably not but the chicks are leaning towards them. They all behave the same way - breathing frequently, and nobody looked to be in distress.

The eggs will help support the chicks and keep them warm, so leave them in for a while longer. When the babies are a older you can remove the eggs if they haven't hatched.

when do you think I should clean the nestbox? Last time, I remember, I got them out for nest cleaning when they were quite older but I can't remember for sure.

Are regular dry seeds, eaten by the parent, really bad for them?

Diane, thanks for ideas.

You can start cleaning the nest box when the oldest chick is a week old. I clean my nest box's every other day to every 3rd day. In the wild, cockatiels nest box's weren't cleaned so it's very filthy. You don't have to clean them but I find dirty nest boxes nasty with all that poop lol.

Sure it gets very dirty and smell is specific too, I just couldn't recall how soon LOL. I remember I was getting pretty big chicks out, while my current chicks are pretty small. I will wait a bit longer. The older chick is a week old tomorrow, but some are only 3 days old.
