How To Improve Your Duck Egg and Goose Egg Hatch RateMarch 11, 2011 |
Modern hatcheries are now adopting the ways of Mother Nature. Only one age of eggs are put in an incubator – just like a hen sitting on eggs in a nest is sitting on only one age of eggs. This is a radical change as the tradition for the past 100 years has been to have multiple ages of eggs in one incubator. If you set duck eggs once a week, for example, you will have some eggs less than one week, some less than two weeks, some less than three weeks and some less than four weeks. This was done so the heat generated by the older eggs was helping heat the younger eggs. |

Temperature: But it has now been learned that by filling an incubator with only one age of eggs, you can provide a much better environment for their development. Instead of providing a steady temperature of 99.5 degrees for the entire incubation, you can start at a warmer temperature (100.3 for our duck eggs) and gradually drop down to a much lower temperature at hatching (97.0 for duck eggs).

Consequences: With our new Jamesway incubators installed the spring of 2009, we are experiencing improved hatches of 2-15% of fertile eggs! In addition, the birds are slightly heavier at hatch (less weight is lost during incubation) and they hatch within a smaller “hatch window”. This allows us to mail a slightly heavier bird that has hatched more recently.
