I have 19 golden comet hens, born in Febuary. I need to introduce 6 others to them, born in June, (1 barred rock rooster, 1 rhoade island red hen, 1 polish silkie hen, 1 aracona hen, 1 aracona/banty mix hen, 1 white, not sure what hen). What would be my best procedure? They have all been in runs, but the 6 have not been close to the 19. Thanks Deb
