Welsummer/marans mix. Lock down was Monday, hatch date today. By 6 AM this morning 6 had hatched (one cull, crooked neck, gasping). Three more try to hatch, membrane is hard, thick, white like paper. I tried to help, could peel shell off very easily but membrane stuck hard on them. They died. Using an R-Com 20, humidity set at 40% until lock down, then 65%. I wrapped pipped eggs in a damp paper towel, it raised the hunidity to 76%. The chicks are peeping loudly and no progress. I can see the membrane where they pipped, it's hard and white. Is there anything I can do to help them?? It breaks my heart to hear them peeping and stuck in their shells. THANK YOU!
