I have a rooster (black copper maran) and two hens (australorp and silver laced wyondotte). A friend gave me two new peeps, both females, of this breed called "Lackenvelder". First of all, these lackenvelder hens are insane--they act more like wild turkeys or pheasants than they do actual hens. I handled them, gave them the same treatment as my other hens (who are loving, tame, and really wonderful, sweet birds), and they are still wild and run from me and freak out everytime I get close. Ok, so fast forward a few months. When the Lackenvelders were 14 weeks old, I tried integrating them into my existing flock. I put them in a smaller coop for a while, then let the birds interact through the fence. After a few days of this, I locked them up in the coop at night. This resulted in one of them getting horribly bloody (back of the neck pecking) in less than 2 hours. They escaped the coop (literally busted through the chicken wire) and fled in terror; I couldn't find them and so they ended up spending the night in the trees before I found them the next day. So I put them away from the main coop for a few more weeks till they got older. They are now close to 20 weeks old; full grown, probably ready to start laying in the next month or so. I tried, again, to integrate them into the flock yesterday with the same method as before. Not only are my two hens beating up on them and plucking out the feathers on the back of their neck, my ROOSTER (who is a real gentleman, the nicest rooster who is so non-aggressive) is ALSO beating up on them. I'm wondering if one is actually a roo, but they both really look like hens. After I saw this behavior this morning, I pulled out my bully hen, the australorp, and left the roo and my other hen, Lima bean, in the coop. I thought that would help them integrate better. No, it didn't matter at all--my existing flock still beat upon the new hens really badly. These Lackenvelders are almost full grown hens--why is this happening? So one is bloody again, and I again pulled them back out and now they are in my garden (which I'll never be able to catch them now, but that's a different matter entirely). Honestly, these chickens have been a nightmare from day 1. Impossible to handle and catch, impossible to work with, fleeing away from you. And my flock doesn't like them one bit. My friend wants to slaughter them--and I'm at my wit's end, and I might take him up on it if a solution can't be reached. Does anyone have any suggestions for how to create a peaceful flock? How to integrate these two birds?
