Lovezebs,
I can't upload the pic of the dad, I see a message maximum 256 kb and the file us too big on the error message :/ will try again later. I think the hen is telling him to have next clutch because he was gathering whatever he can see from the cage floor in the nest, so this cause the hen to do something bad to the babies
I even took down the nest because the hen just nonstop by pluck on them whenever she looks at the babies. Then I decided separate her to the cage next to it, I cleaned the nest since too much poops, didn't want any infection or bacteria on these babies. You can see the pic below much cleaner than above pics! I even CHANGED a bigger size since 4 of them don't want overcrowded

The parents doesn't mind I touch it and even calling me sounds like " where are my babies"? By looking at the place where the nest should be lol. While they looking for the nest especially the daddy, at same time I put the babies with nest on floor with a fluorescent light keep them warm when change the nest carefully, and used disposable spoon to scoop one by one to the bigger nest. ( indeed doesn't fit the spoon anymore because they are getting bigger now, have to use my fingers to help

)
The dad immediately feeding on the babies after I put the clean nest back, so everything looks ok. I don't wanna disturb them unless have to, like yesterday the hen is really picking on the babies which I see it with my own eyes when observed her. I will update it here next time if anything changes. Thank you for reading my post!
