I counted day 1 as the day I set them. So would I still be on day 20? And tomorrow will be day 21? Still learning and trying to read up on everything but haven't heard anything about that
I believe you are on day 20, day 1 is counted after a full 24 hours of incubation. Let's say (for example) you set the eggs on Monday at 9am, day 1 would be Tuesday at 9am, day 2 would be Wednesday at 9am, day 3 would be Thursday at 9am and so on....
Hearing chirping and seeing wiggling sounds perfectly normal for day 20, good luck
