My Duck mama has been sitting on eggs for 34 days now... one finally was trying to hatch and didn't make it, now another is trying to hatch, it has about a dime size of broken shell (like you break shell before you are peel a boiled egg) and that has been for about the last 24 hours. A little bit of the shell has come off in two places. The membrane looks very dry and brown... like brown paper. The duckling is still peeping. The mama duck has the egg turned so that the cracked part is facing down. Any advice is GREATLY APPRECIATED!!!
