I integrated 2 16 week old pullets with 3 16 week old pullets..the first 2 days were rough...a lot of fighting and pecking. By the 3rd day they settled down a bit..but still chased and peck. So now 2 weeks later..they still stay in their original flock..once in a while they r all together..when i bring them treats..1 of my pullets allow the others to eat but grunts and scares them away every few seconds...one of the girls from the other flock wont back down and chases the passive girl...WILL THEY EVER JUST ALL GET ALONG AND SHARE AND PLAY NICE?
