Hatching eggs - Mom won’t sit on eggs any longer

[Bjski]

I got my first chickens about 9 months ago. I have 3 hens and one rooster plus 3 newly hatched eggs. They are all Plymouth Barred Rock
I went on vacation and came home to a chicken sitting on eggs, so got into the breeding process rather unexpectedly. I’ve been searching on line forums because I’ve had a rather distressing couple of days with 3 live births another 3 who were apparently eaten before I found them and now one that was abandoned during hatching.
I have a number of questions about what I am doing wrong, what I am doing right and how I can save the rest of my unmatched eggs.

Ok, replying to my own post. I know now that you aren’t supposed to have staggered hatch dates, but how can I help the remaining eggs to hatch. I don’t have an incubator. Do I just keep putting mom back on the box? I had 2 hens that were sitting on the eggs, but after losing 3 babies in a row, I removed one of the hens. I tried to give her some of the eggs to sit on, but she wanted nothing to do with them. She only wanted to be with the one hatched chick. Although when I put her back in with the baby, she was very aggressive.
