So I'm getting ready to move my new babies: 3 silkies (by attitudes only I'm thinking 1 roo & 2 pullets) and 5 lavender orpingtons (I'm thinking it's 1 roo & 4 pullets based on comb & wattle growth & color). They are 6 weeks old tomorrow and all hatched/brooded together. They've done pretty well getting along to date. The two potential roos have butted heads a few times, but overall they've gotten along swell. So I'm wanting to merge them into my coop with the older flock = there are 5 in there right now, two almost 19 week old white leghorns (1 roo & 1 pullet) and three pullets (1 Ancona & 2 unknown potential EEs) that are 15 weeks old as of yesterday. Here's a pic of my babies running loose in the run. I've had all of the ages together in the same coop for two weeks now but the babies are sectioned off on the right side with hardware cloth and chicken wire. And they have had a few times of outdoor play in the run when the bigs were locked outside the run. This morning I left the run door open by accident and the WL pullet came into the run while I was cleaning the coop and the babies were loose. She chased a few and pecked at them. I expected she would do that because she's the head hen. So I shooed her back out and the babies ran around for awhile longer safely. Then I put everyone back in their perspective areas. I'm not worried about my lavender orpingtons I think they can probably take a few pecks on the head and survive - but how deadly would it be for the silkies to get pecked? Just how hardy are the silkies' heads? Do I have to move them to their own coop/run or can I keep them altogether and just keep a watch on them? Anyone have success merging and keeping silkies into a mixed flock?
