Its day 28 and none of my 3 goslings have broken into the air cell yet. 2 were still trying as of last night. And those same 2 were trying the night before too. Are they right on schedule? I thought they all would at least be in the air cell by now. Can anyone tell me how long they can take to break into the air cell, and then how long they can take once in the air cell to start pipping, then how long they take to hatch? In other words, how long does each stage of hatching normally last? Thanks! It's my birthday today and i was hoping to at least here a peep out of them!!!
