We have had a hard time with our eggs, as we were letting the momma sit on them, but many died. We think it was the moisture conditions in the house. We had one last egg, but it was accidently knocked over and broke. It looked hopeless, but we opened the egg and the little one (within a day of hatching is still alive and breathing, although the inside of the egg is totally exposed. The yoke is attached, and the little guy is breathing, and occasionally chirping. We immediately put him in an incubator . My question is what temperature and moisture levels should we keep considering that this fetal duckling is completely exposed? We have her next to the enclosure with our 3 newly hatched Cayugas, and they are communicating, and we recorded sounds off the internet of a momma muscovy and her chicks, and are playing them on a loop. Please can anyone give us sound advice. this is our first time trying with ducks, and this is Jerusha's last chance at being a momma to her own flesh and blood. It seems like a miracle that the little one is still alive, and we would dearly like to keep it that way. Yours; -Evelyn and Peter.
