Serama hatching issues

[chickengang11]

Hello everyone! A while ago I found 2 broody seramas sat on 3 eggs, candled all of them and they all seemed to be fertile. I don't know how long they were sat on them, but 1 has hatched just yesterday and seems to be healthy. The other 2 haven't shown any signs of external or internal pipping. I haven't heard any chirps from either of them, and when I tried the water method there was a tiny wiggle in one of the eggs. I don't know if I should be concerned, but I'm quite new to hatching, so I'm sorry if this is a dumb question. (Also, if needed, I can send candling photos) Thank you!!
