It is definitely a learning experience, hard as it is. We have had 3 broody hens. 1st one sat on those eggs faithfully. One busted and ruined the whole batch. They all died in the shells
. 2nd broody got tired of sitting and quit after 14 days
. 3rd broody sat on 6 eggs. 3 hatched out. We gave one away. The other 2 and mama are in my avatar pic. I hope your remaining chicks make it. If mama hen is not doing her job, I would grab those chicks up and put them in a brooder box with a light. Good luck. Please keep us posted.
