So i have had 2 broody hens. First one breaks most of hers eggs and other almost all od other broody hens eggs. Dont know why .. they have each their box.. so from first brood only 3 left on day 7 and then she get up and breeks eggs and stop being broody . my other broody was on day 10 with only 2 eggs remain but she continue being broody . So i put 3 from first to her.. today is day 15 for first 3 eggs and day 18 for 2 hers eggs. All eggs develop good. What should i do when first 2 hatch?
