Frequency Of Fertilised Eggs and prevention of development

[MaggysEggsAidan]

I have a nine week old rooster and 8 other hens and i was wondering how when there older and sexually mature if there are any techniques I can use to prevent the eggs developing, also I was curious to what the number of fertillised eggs to unfertillised eggs would be roughly.

Ratio of fertile/non-fertile depends on ratio of roos to hens and the fertility of both. 1 to 8 means most will be fertile if he's fertile.
If you don't incubate the eggs they won't develop.
You won't notice the difference.
The egg has to be in the 80s for a while for cell division to begin.
No serious development will occur unless in the mide 90s or above.

As said, the likelihood is they'll all be fertile. If you don't place them in an incubator, nothing happens. The fertile egg takes a very trained, well focused eye to even see the tiny, tiny speck. It's nothing. No concerns about the egg developing unless you take pro-active steps to encourage it.
