Why hello there!!! I have 7 chickens-- three hens that are 3 years old, and four pullets that are four months old... I'm going to integrate them after I get back from vacation on the 16th. I really wanted to try the roost theory where you put the ones you're going to integrate on the roost late at night... Then the hens are supposed to wake up and just kinda go along with it. The problem is-- my hens have seen my chicks a TON. They would free range as two different flocks, but they would sometimes cross paths, and my hens would chase them off. They're kind of aggressive hens too.... I wanted to try the theory cause it sounded like a quick and *almost* painless integration process if it worked. But I know that it's a total gamble. Should I try it?! If you have done that then PLEASE let me know how it went and if you liked it!! ESPECIALLY if you have aggressive hens!!! Mine are as sweet as can be to each other, and to humans but not the nicest to new chickens... They normally chase them off and grab a feather or two then leave them alone until they get out of the hens' way. So they're not like peck-them-til-they-die sort of aggression, but they're just not very nice. So PLEASE tell me how your integration process went and what you did ESPECIALLY if you had aggressive hens!!! Thanks!!! -chickencrazy429
