Wish my baby luck shell accidentally got broken by hen so I took it out and now am keeping it warm but I don't have my incubator as my daughter borrowed it and she lives over 2 hours away. Heating packs and microwaved moist wash so hopefully it will live
Good luck little one
You can use Vaseline to keep the membrane moist
Even a little kitchen plastic wrap over a big portion just leaving an area open for where babies beak is
I wouldn’t wrap it just set it over the area
