I'm using the Ganggend 36 incubator, it has adjustable auto rollers. The rollers can be adjusted to be used for duck, chicken, pigeon, quail, or whatever. It has temp and humidity control as well, Humidity plays a large role in success rates I've read.
This is my first time incubating anything, I've always just bought chicks. Despite the power going out at least twice during incubation due to massive storms, out of 24 eggs ordered, I got 10 chicks, so it could have been better but it could have been worse. I'm hoping for better hatch rates next time but 10 is enough to get me started.
I bet your fertility rate was down due to the timing of the loss of your rooster.
Good luck! Your plants are looking good as well!
