I have 24 hens(4-6mo) and 6 roosters(5mo) as well as 4 guinea fowl(2mo). I’m wondering the best way to integrate the 4 guineas into the already established flock of 30 and if they’re old enough to be introduced in? My hens and roosters vary in breeds. We have Golden Comets, White Leghorns, Australorps, Bantam Cochins, and Easter Eggers. Any and all advice would be lovely! Thank you in advance!
