Ok, please all suggestions welcome! I just completed my third batch of lavender amauracana hatching eggs today. All three times I have set from 20 to 35 eggs and each time adding a handful of marans or seramas as a reference guide just to make sure it wasn't just an amauracana egg problem. At each hatch I have gotten all to most of my marans, most of my seramas and only a single amauracana in each of the hatchings. I have been hatching eggs for about five years and have always done fairly well, till now. These are the things that have changed, I downsized to a single foam incubator, forced air and turner. I only recently added the amauracanas to my flock and they began laying this summer. I have three hens and one roo. One hen lays daily, one hen lays a couple days a week....... Maybe, and the third hen I can't say for sure has ever laid an egg at all. The incubation seems to go well with fertile, developing embryos in 85% of the eggs. Incubation is at 99.6 degrees at egg center level and humidity at 45 to 50 % and raised to 60% at day 18 for lock down. The problem seems to occur about the end of week two or the first couple days of week three when, for what ever reason, almost all the embryos/chicks die. What is going on? And why do I keep getting one healthy amauracana chick out of 20 to 30 eggs in each hatch? I'm so frustrated. I need one really good hatch to fill out my flock.
