My guineas are too young to lay, they're barely over 3 months. I have 9 Runner ducks that are just turned 5 months that haven't started laying yet and an 18 month one that hasn't laid since 8/6/20. My chicken hens are only ones laying and I've got 9 juveniles expected to start laying by spring. It will depend on if any of my hens go broody. No broody hen, no hatching eggs. I don't use an incubator.
