Hi, It's Jennifer. Sorry to hear it is taking time for everyone to get used to him. When I introduced a couple of silkies to my standard flock I seperated them during the day, but made it so everyone could see each other. then, at night I put the 2 girls in a cat cage and had them sleep in with the big girls. I did this for about 3 weeks. I finally put them in at night with out the cat cage and they did go after the little ones the next day! It took a couple of weeks for it to get bettter. I made sure there was a spot in the coop for the little ones to hide if they needed to, where the big chicks could not get at them. It will work out eventually.
