Day 28 is the day when hatching starts. When I hatched my welsh harlequins there was no sign on day 28 and it took over 2 days for them to hatch. It's a long process. Be patient. It's not a good idea to open the incubator after lock down because the drop in humidity could cause them to be shrink wrapped in their shells. I know it's tempting to take a peek and it's very hard to be patient but you need to give them more time.
ha ha ha! That's brilliant! A little more patience. The others will start hatching soon. They take a long rest after breaking through the shell so don't be surprised if that one does nothing now for hours. It's very tiring for a baby duck to hatch out of a shell.
Is this normal?
The other three I would have expected them to have pipped internally by now. I don't know what to suggest in this instance. If one of your eggs is pipped at the wrong end there's a possibility they might be too. Sorry this isn't much more of a help to you. Maybe hold them in a damp paper towel and candle them and try and identify where the air sack is and if there are any signs of life. If the air sack isn't at the blunt end they maybe struggling to pip.
Thank goodness it's still alive.
one low floated but very little movement and one low floated and was wiggling everywhere. Still no sign of internal pip unless we're just not seeing it
