I need help. Everyone but me has sucess hatching duck eggs or waterfowl eggs. I've set untold amounts of goose, muscovy, and Welsh Harlequin eggs this spring and none have hatched. Earlier in the year when I was still in school, I can understand what went wrong - I didn't have time and often forgot to add water or turn... so of course they died. However, this batch I've been turning 3x per day, and keeping humidity around the upper 50s - around 57% or so. It DOES vary slightly when it rains etc, and there's nothing I can do. Seems like this would be fairly normal with natural nests, too though. Temp stays steady at 99*. The incubator is in my basement where temps are fairly constant. I started out with about a dozen welsh harlequin eggs in there. They died off sporadically, leaving me with just two that made it into the final week. I just candled them again and I strongly suspect that they are also dead. FERTILITY is great, ability to live till hatch is very poor. With ALL waterfowl eggs - even muscovy, which when naturally hatched all 20 in a nest will hatch so I KNOW it's likely my skills. I have some Welsh Harlequin eggs underneath broody muscovies so we'll see how those do. What do I need to change? I've tried spritzing clutches - that didn't help. I've tried higher humidity, that didn't help.
