Out of 4 eggs. 2 have hatched. This is day 20. Both chicks were in the bator until dry. I quickly took them out because they were knocking the other eggs around so much. The humidity is still reading very well. They are doing great. However, my question is, one of my other eggs was moving two days ago and I haven't seen any movment since. I have been at work throughout the day (I missed both hatches). But there are no external pips. Should I be concerned that i haven't seen it move? Should I candle? Thanks in advance.
21 days is just a guideline for eggs nothing is set in stone with incubating. I wouldn't candle them yet you need to keep the humidity in your incubator opening it will let it all out and it's better for your eggs that havnt hatched to have the humidity stable. Chicks rest a lot during the hatching process it's very tiring for them. You could just have missed them moving. You probably saw more movement two days ago because that's when they move the most when they are getting into position to do their internal pip. They then rest before doing the external pip. Then rest before zipping. Try to resist opening the incubator it's not time to worry yet. Wishing you the very best of luck
