Needless to say, out of 18 eggs, 8 hatched and it turns out all 8 are ROOSTERS. However, a room can easily be around 55-65 and still have a successful. I did have issues with humidity at first but in about 2 days it got better but never actually stayed in the sweet spot. An ideal ambient temperature for the room your incubator is in should be around 70-75. The temps in the incubator were about 3-5 degrees cooler than they were supposed to be, (I forget off hand the temp). I put them into my incubator and away we went. I kept them in my basement for 3 days (longer might make a difference). I collected 18 eggs about a day or 2 old, picked the roundest ones I could find. I didn't get the results I was expecting. Turning the eggs will prevent the embryo, which sits on top of the yolk, from floating to the top and sticking. If you are using an automatic turner, remove the turner at then end of day 18. I emailed you once before to find out how all hen hatching went for you, and you couldn't remember. Days 19-21 is called lockdown, when the baby chick is positioning itself for hatching and chicken eggs are not to be turned. Has anyone else tried this method? If so, I would love to hear your results! Candling your eggs on the 7th day of incubation is an important part of the process. During the final 4 days of incubation, the humidity is increased and temperature is decreased. I really find this kind of information fascinating. Your eggs will need to be consistently incubated at 37.5☌ (99.5☏) up until 4 days before hatching. ![]() I'll be interested to see what my male/female ratio ends up being out of the eight chicks I hatched.Īlthough all eight that I set did hatch, so unless they were all female eggs, I'm thinking either they weren't stored for long enough at a low enough temperature or the incubator temperature needs to be lowered for the entire incubation period. And think of it this way, if you do have a rooster in your flock and eat your chickens eggs, youre likely eating both hens- and roosters-to-be every day. I also did lower the incubator temperature a bit for the first few days of the incubation period. Since I ordered my hatching eggs while the temperatures were still cold here in Maine, I wouldn't be surprised if they got down to around 40 degrees at some point during their journey. I really find this kind of information fascinating. And think of it this way, if you do have a rooster in your flock and eat your chickens' eggs, you're likely eating both hens- and roosters-to-be every day. It's clearly far more humane to just not even let the eggs hatch than hatch out unwanted roosters. 380�382) purportedly demonstrated sex reversal in chicks in ovum by pulsing eggs with higher or lower temperatures, but the results were never replicated.Ī much more recent study published in 2013 (Poultry Science, Volume 92, Issue 12, 1 December 2013, Pages 3096�3102, ) found no evidence of temperature-dependent sex determination or sex-biased embryo mortality in the chicken.So you'll likely have a lower overall hatch rate, but what you do hatch should be a higher percentage of females.Regardless of your views on when life starts and all that, it's a sad fact that most roosters don't meet a good end in life.Įven those people who keep roosters in their flock don't keep an even number of roosters and hens, not even close, so poor roosters are pretty much doomed from the start. 1994 Temperature dependent sex determination in reptiles and manipulation of poultry sex by incubation temperature. At the time of this writing, we have not found a study that replicated this result.Īnother study (Ferguson, M. It was postulated that the male embryos were preferentially killed off by colder storage temperatures, while the female embryos handle the chilling better. Wouldn't it be great if you could incubate and hatch all females, or at least hatch a much higher ratio of females than males? Sure!īut as we shall see-don't get your hopes up just yet.Īn Australian study published in 1960 (Australian Journal of Agricultural Research 11(4) 664 - 672) found that eggs stored at 40 degrees Fahrenheit (rather than the recommended 60 degrees) for at least 24 hours and up to 7 days before incubation hatched out 54.6% more females than males. For most backyard chicken enthusiasts, females are preferred for egg laying and unwanted roosters often have to be rehomed. The question of temperature-dependent sex determination (TSD) in chickens has been an important subject for scientific study over the last several decades.
