I picked them up from seller. Incubator has turning function, have put them in for first day today. Silkie eggs. I would assume they are all fertilized as the advertisement said.Other factors come into play. Were they shipped? Were they turned? How have they been handled? Breeds? Fertility of flock...?
I have hatch my own aged eggs (30+ days, some refrigerated, some sitting on a hot kitchen counter, never consistently turned..) with moderate 20% success. Throw them in the incubator. You will do well if you end up with 33%.
I am a first timer. I bought half a dozen of freshly laid of another species. This half a dozen is Silkie eggs, when I saw the dates written on the shells I have this question.What is your reasoning behind wanting to know the predicted hatch rate?
Are you trying to limit how many chicks hatch and would put in less eggs to achieve that if the rate could be predicted high? (What would you do with any eggs not put in-consumption/destruction.) Are you trying to get to a certain number of chicks and would go get more eggs if predicted low? Have you hatched before and what was your hatch rate then?
I also would predict a lower than “normal“ hatch rate, maybe 25ish%? But personally I hatch mostly to get new hens so I guess a hatch rate, then assume about half will be males, and possibly a chick that just doesn’t thrive, and I’m going to want to get a breed to two I haven’t had yet,.....so I have a bad habit of putting in more eggs than I intended to.
Noted. Thanks for sharing.I did this when I had to dispatch my rooster. 14 eggs over 12 days, set the 13 (after I dispatched). Stored and rotated properly. Many were porous when set. I had 2 hatch and 2 die on day 20. Both from different days, one at 2 days of collection and the other at the 3rd to last. It is possible and I hope to hear your results.
