Hens go broody when you don’t want them to… and won’t go broody when you do. 
Hello EggSighted4Life,
I just read your comment on another post indicating that you breed chickens, here in Oregon. Since many vaccines are now MRNA, and we would like to avoid that, we want to get chicks or hatching eggs from a line of chickens that has been unvaccinated for a number of years. I'm not sure if this describes your operation, or if you are even still breeding chickens (the post was from 2016).
