Life is a nightmare! Today some chicks fledged, and I think chicks who are not in the box confuse the parents (plus one parent sits with her tail up). I fed the chick who fledged and was begging for food, but I can't say he was eating well. Rather, he tried to follow the parents. Thermometer I bought yesterday has failed today.
I have a big project due tonight, that I haven't started (not that I was lazy to do it before). I am offering you, big birds, help by providing you with nice food around the clock. I am offering you, little birds, help by feeding you formula. If all of you don't appreciate my help, I will leave you alone to do MY (project) JOB (while your job is feeding YOUR chicks)
That's it.

what am I to do with chicks who got out of the box? Some just sitting on perch or bottom of the cage doing nothing. I gave them bowl of water, millet spray, some seeds with pellets on the cage floor, but they don't eat yet. a few hours later, I put them back thinking that parents would more likely feed them there.
IS it correct that as soon as the last chick makes his way out of the box into the cage, I can completely remove the box?

It's OK to put the chicks back in the box periodically if the parents feed them better there. It's also a nice safe place for them to sleep at night. You can remove the nest box as soon as the youngest chick is out of the box, especially if he's comfortable being out of the box.

Chicks usually adapt to handfeeding better if you start when they're two to three weeks old. When they're older than that they're more resistant to it. This same problem happened last time because the babies were older when you started trying to handfeed them. If they have more babies in the future (hopefully not this year!) it will be best to start handfeeding the chicks at a younger age so they'll cooperate better with you when the parents start slacking off.

I probably underestimate the feeding work the parents actually do. All the chicks measured more weight today than yesterday, and some had a crop so full that I immediately took them back to the box without feeding.
Two older pied ate well from me. I didn't feed the youngest - he had enough. Younger cinnamon reminds me fussy pearl sister from the first clutch - she shook her head the same way when I fed her.
SOmething strange was about the bigger cinnamon. She was so frequently breathing with her crop that I got scared. I thought could the formula be a little bit too hot? I don't rely on thermometer, I try on my wrist. I thought the temperature was OK but who knows... Another version is that she had too much in her crop that eaeting more caused her shake her crop (its when you see how only the crop is moving up and down). WHat could it be?

I don't know exactly what you mean, but it might have been muscular action as food was moving out of the crop and into the lower digestive tract. You need to be very careful about the temperature of the formula, because if it's too hot it can burn the chick and cause serious injury.

I know that. I test on my wrist and think its OK when it feels warm, but not hot. Is it acceptable?

You need to read up on the rights and wrongs of breeding...

Using a thermometer is best since it's more reliable.

I would disagree as any device can fail and my thermometer demonstrates it.

where is this?
