Hello. I'm ready to order an incubator and hatch eggs for the very 1st Time! I've been doing a lot of research, but figured who would know best about what incubator to get, and how to do this, then all of my intelligent, experienced chicken friends here at BYC! So here are a few questions that I have: 1) Still Air incubator or Forced Air. Which is better and why? 2) Cheaper incubator versus more expensive. Is there a big difference? 3) Fertility. How can I tell if my eggs are fertile? Are there certain signs to look for? If you guys could please share your opinions, tips, advice, suggestions, and most importantly, your experience on what kind of incubator to purchase, and how to get started by choosing the right eggs, and hatching eggs I would REALLY appreciate all the help I can get before getting started. A little bit of back ground on myself; I've owned chickens for one year, my current flock consists of 25 chickens, all different large breeds, Rhode Island Reds, Golden Comets, White Leghorns, Ameraucanas, Wyandotte, Barred Rocks, and my second, smaller flock, consists of 7 bantams, Silkies, Cochins, D' Uccles. I am currently raising 3, 10 day old Bantam chicks inside in a brooder. The eggs I would like to hatch are from my larger breed birds. All of my hens mate with my rooster on a daily basis, but I don't know how to tell if they are fertile. Thanks so much for reading!
