We had a pair of Muscovys sitting on a shared nest, last wednesday was when the eggs were due to hatch but by Saturday there were still no signs of life. When I came back from work on Sunday afternoon I saw that the 2 ducks had left the nest and were in the yard but as I walked past the chicken house I thought I heard faint cheaps. I went in an took a look at the eggs, there were no duckings or hatching eggs but I could hear cheaping! So I rushed inside and turned on the incubator, alerted my brother who said the ducks had been off the eggs for almost 3 hours! We put all 20 eggs in the incubator and by the monday morning there were a few that had pipped externally. Now on Tuesday afternoon there are still no hatched ducklings, none are even close, but these eggs are almost a week over their due date! I am worried about exaustion and suffocation, does anyone know if Muscovys are very slow at hatching? Or do I have a problem, should I help them out?
