My broody hen nested in our horse hay. Around week 3 I started finding empty bloody shells once a day. So I covered the area with a large chicken wire cage thinking it was predators. But the pattern continued. So I brought the last 6 eggs in last night and put them in my incubator. I put some fresh eggs under the hen and left her be. One chick hatched today and the others are pipped. Should I try to introduce the hatched chick?
