I had concerns about mixing them with my flock, but so far they've done fine.... I have 2 Ameracaunas and 2 French Marans. Now my SFs outnumber the others!
The Ameracaunas are ruthless biddies, in my opinion, but they don't attack - mostly they don't let anyone in the coop when they lay or around the feeder when they eat, but I have multiple water/feed spots... At night, they all share the roosting spots, I have plenty of those too...
The French Marans are busy raising kids right now, so they're a little uptight toward everyone, but I expect that to go away...
My Favs have not lost any weight or had blood drawn, they lay regularly and seem in good spirits, healthy and vigorous.... Myabe I just got lucky
I think part of it was because when I introduced the SFs, I made a lot of changes - to distract the other birds, sort of... I was aware of potential problems. We just built the new coop, so everybody was new to it - then I adjusted the "furnishings" inside and changed the bedding to throw off odors, etc.... and the chicks hatched, so the broodies were in there too.... Quite a ruckous! It was a great time to integrate new birds.
