I'm worried about my chick's. It's day 17 and my marans eggs look perfect. The other breeds only look like it's on day 14 or 15 when comparing to other pictures. Not sure what I should do. All are alive and moving. I've had the temp probe in a water wiggler at 99.7 on average with 30-40% humidity. Should I continue with lock down tomorrow even if the other breeds seem to be a bit behind? I hope they all hatch..
