Hi all!
New month, new hatch-a-long! (sorry this is a long post)
This month I will only have one hatch, but it'll be a big one. 40 muscovy duck eggs are due the 8th. I've had THE worst luck with the ducks this year, many late deaths.
I've identified 2 problems: insufficient turning since I put them small-end-down. This time they're on their side, and an additional 180 degree manual turn each day. 2nd problem I noticed when I first candled the eggs. The bottom tray had 5 undeveloped eggs, while the top had none. All duck eggs have been incubated in the bottom tray. I've swapped them twice a day from day 7.
I found this article: Artificial Incubation of Muscovy Ducks (pdf link at the bottom) that found a correlation between egg size/shape and late deaths. The late deaths in this experiment were smaller and lighter than the normal hatches. I decided to put that to the test and measured all my eggs.
The average egg is about 6,6 cm long and 70 grams.
(L on the side means small air bubble. (smal = narrow, rund = round, spiss = pointy))
I also marked their air bubbles, which are a bit small for my liking.
So now I'll wait and see...
