If none have hatched, day 22 isn't bad. (cooler weather, a broody got mixed up & sat on the wrong nest for a couple hours, power outage in the incubator, slightly cooler incubation temp, etc. can all delay the hatch) It's only time to be concerned when you've had 1/2 hatch out early or on time & then you're on day 23 w/ no pips in the remaining eggs. If nothing has pippeed, then they could just be a late batch.I tried the water test with my Dom eggs today day 22 and it seems they are viable eggs but there was no movement. If they are alive should there definitely be movement? Super attached to these little eggs but losing faith.Also used a flashlight and didn't see any movement. Wishful thinking or could they still be alive?
Using the same incubator & settings, mine usually pip day 19-20, & hatch day 19-22. Been doing it for years. Back in March this year, I had a group where nothing pipped until day 22. Then they popped out all at once on day 23. 10/12 hatched. Not sure why & it was the only time that happened. Perhaps it had to do with the weather when the eggs were collected. I was going crazy thinking that all were bad even though I had candled & saw good development. I rarely see movement past day 17. Things are just too cramped for the chick to move easily. If the egg is mostly black - except the air cell- consider it good & put it back into the incubator. (BTW- When I was worrying about my own late hatch, I had others share stories of day 24-25 hatchings.)
