Hi, new member here from Puyallup Wa. I am new raising chickens.. I currently have a Silver Laced Wyandotte and a Black Sexlink that are 5 months old (I raised them from hatchlings)... And I just acquired 4 new pullets today: 2 Gold Laced Wyandottes, 1 Gold Sexlink, and 1 White Leghorn that are all only 10 weeks old, and about half the size of the two older girls. Upon their introduction this afternoon, there was some pecking and bullying being handed out by the big girls to the little ones. They are all free-ranging, so the little ones had plenty of running-away room. They were not introduced to the coop. But, to my surprise, this evening the little ones hopped up into the coop and onto the roost next to the big girls. They are sleeping next to each other for the first night (hopefully peacefully). Even though things seem to be going smoothly, I am still worried about the little ones because of the size difference. I just hope this new pecking order is established quickly, smoothly, and as peacefully as possible. As this is my first time in this situation... Does anyone have any advise to help make this a smooth transition? Any help will be greatly appreciated! Thanks!
