Yes, as suggested as long as teh membrane is still intact, you can tape over it. I've seen some people use wax, though I'd be more inclined to try tape.I've got the temp stabilised. It's Day 10. Today I dropped an egg while turning it and it dented one it fell on. I feel so bad!! Should I leave it? Will the inside membrane be tough enough to protect the chick? Should I wait and see if it starts to smell? I'm such a klutz!
