First time for me and the hen hatching eggs

She chose her milk crate nest box to start getting broody in. I left her until it was time to give her a singleton I hatched a few days before her eggs were due. Moved her into this broody station in the video. They started hatching last night. Two fell out onto the ground. I picked them up put them back. One seemed terribly small. Late last night I checked her and she smooshed him stuck to her foot. This morning a different baby fell out so I removed the milk crate. All seemed great until I just went to check and she smooshed another in its egg shell. She’s been great with the baby I hatched and gave her. I believe there are 2 more not smooshed but hatched… should I take the eggs she’s got and put them in the incubator to finish hatching or just let nature do its thing ???
