Can someone explain the cooling and misting of Goose eggs in incubation?

Good to know about the cooling . I have 5 geese and 3 duck eggs in , that were good after candling them, day 9 today, Started with 7 geese and 12 duck. Only done Chicken before, and no problems there, So this is new to me, Had a pet Chinese Goose for 19 1/2 years, Miss him so need another one

Hi All. Just to clarify things I thought I'd try to explain a little more. We believe in cooling eggs for a higher sucess rate and believe it helps to increase the rate of moisture loss from the egg as it 'contracts' during cooling. The cooling can be enhanced further by a light mist of water onto the shell and left to evaporate.

The cooling appears to benefit the egg in three key way;

• Increased rate of water molecule loss which helps to achieve an overall 16% weight loss.

• Increased rate of gas molecule exchange including carbon dioxide loss.

• Loss of excess heat from larger embryos as their metabolic rate increases with growth

To help clarify I would recommend the following programme;

From Week 2 - cool for 10 minutes daily
From Week 3 - cool for 15 minutes daily
For Week 4 - cool for 20 minutes daily

Eggs can either be removed from the incubator for individual cooling or the incubated opened and turned off for single batches. We lighlty spray the eggs at the beginning of the cooling period.

I have 9 duck eggs in an incubator in my garage. I need to start cooling today. Does it matter that it’s cold in the garage, about 40-50 degrees? Should I still be doing the same amount of cooling time or carry the eggs inside to cool off? TIA

It would be the same temperature if the hen got off them to eat and drink. They'll be fine.
