I'm hoping someone can help me. I'm incubating 4 Welsh harlequin duck eggs. This is my first hatch, from postal eggs We are on day 28. Out of the 4 eggs 2 have pipped. Egg 1 pipped over 38 hours ago - I can see him poking his bill out on occasions and he is making very very slow progress. Hole is very very slowly getting bigger. The inner membrane looks dry and flakey around the opening. Should I help him along tonight? Egg 2 has pipped once yesterday and again another small pip over night, so now over 24 hours and still no further along. The other 2 eggs have not pipped at all yet. I can hear peeping and some tapping - not sure who from. Again do I need to do something? My worry is they've got "shrink" wrapped due to low humidity like I have read. I have no way of measuring humidity on my incubator. Have just kept the water topped up and sprayed them before lockdown. I very quickly added some extra water this morning (not lifting whole lid off, just a corner and quickly pooring it in a few seconds max) Is there anything else I can do? I really don't want to lose them and am so anxious!
