My Pekin Duck, Sits on eggs since last 4o days, her eggs started a hatch hole since last 3 days, but

Furthermore, I tried to assist hatch, but found teo memberances a little bleeding in shell, and put the eggs back under the duck, duckling was struggling to take out, But i left the second shell as it was, after increasing a little tear. by the way Its very complicated ,since 3 days, they made the same progress.. no further hatch, that's why i made it clear to assist them, i am still worried with a little blood on memberane, will my ducklings hatch and survive, coz i acted on air cell, the lower part is still in tact with them, any guidance?
