I have been trying to hatch Muscovy eggs in an incubator with terrible results. I have hatched many types of chickens, Call ducks, and goose eggs with great hatch rates. Also read that Muscovy eggs do not do well in an incubator. so I decided to oder another batch of Muscovy eggs and put them under a broody chicken. I had 2 broody chickens at this time, so when the eggs came in yesterday I removed there eggs, placed them in the incubator, and put the Muscovy eggs under the chickens. So now I need the estimate the chicken eggs hatch date so I know when to stop turning. I have printed the pictures from BYC of the eggs from day 1 to day 18. I will use them to get the most accurate age of the eggs by candling them and try to estimate the hatch date. If I am off a bit, how detrimental will it be to the eggs? Any other suggestions on getting the hatch date as close as possible. The chickens are a Silkie and Frizzle, both bantams, so I gave them each 6 Muscovy eggs to set on. I did't think they could handle more than that as the eggs are MUCH larger than their eggs.
