I have read/heard that leaving about a dozen decoy eggs in a nest box can get a hen to go broody. Has anyone ever had any luck with this? If so, is there a prime time of year, like say Spring, that is best to do this or can it be done any time? My young roo just started mating with my ladies and I'd like to hatch out some chicks. I'd rather a hen do it than an incubator.
