It makes some sense in a fashion, and completly confounding in another.
the old timers I get info from have YET to be wrong! But they haven't heard of this having a better or worse effect.
they say its all a crapshoot until you find someone who knows hatching inside and out to sell you the desired eggs within a pick-up distance, because the post office is usually city folk who have no clue how to handle eggs or animals or anythinging to do with "an honest living"
These guys crack me up with what they say a lot of times, but they are an encyclopedia of information for fowl!
hmmmmmmmm........anyone want to experiment with this one? have two control groups using eggs you know have a good fertility rate. put them all in the bator, 24 hours later remove half for a day and then incubate all as per your normal. i may try this myself.......just to see. 'course it will have to wait until i actually have space in the bators lol
He didnt say where he was incubating. He said a friend of his ( that has past on) did a 25 year study(personal) of this and his success rate was much higher when the eggs where incubated first.
I will keep you posted, because I just ordered eggs from Shadeglade on BYC and asked her to do that for me and she said she will.
