I have heard that pea hen eggs are most venerable in the first week, I think they need more turning than chickens but could be wrong.... I do know one one very large breeder that uses Broody Cochin for the first week of incubation and then moves them to the big red-wood incubators and he is getting 99+% hatch rates with this method.... and he keeps over 100 broody Cochin just to start all of his pea chick eggs!!!!!!
