My duckling is on his third day hatching and is out of the egg now after a long assisted hatch period but has an unabsorbed egg yolk still attached, I saw it this morning and left him in the bator on a warm wet cloth but it dosent appear as though any has absorbed and the yolk sac looks a bit more redder then the yellowy range as it was this morn. Iv read that you can tie and snip the yolk sac off, do you think I should or should I leave him alone for a bit more? I so don't know what to do? I really want him to survive but hes not up and moving about hes just laying on his side in the bator. He lifts his head and peeps and lifts his wings but iv not seen him stand at all.
