Thank you for your kind reply. You always give me a glimmer of hope but then I wind up facing the reality of my flock's hen-pecking politics LOL!My flock is entirely mixed, and kept all together. Large fowl, a few bantams, silkies, Breda, even my peacock and turkey hen.
My Breda is a little bit of a loner, always has been, but I've never had any type of fighting.
My meanest one is a Golden Laced Wyandotte if anyone tries to eat at the same time as her, she will try to peck at them. Everyone else gets along fine.
But I have silkies, Ameraucana, Easter Egger, Olive Egger, Breda, Leghorn, Wyandotte, Barred Rock, Orpingtons, Marans, bantams, etc. all together.
My flock is bigger than yours, but still small. There are about 20 pullets/hens all together. I have a ton of chicks right now, but they are separate. I also have a meat pen, but that's in an entirely different part of the yard. Ducks have their own run as well since they dirty all the chicken's water.
I used to let them all free range, but my yard is small and the flies were getting ridiculous with them pooing wherever so they're in the run the rest of summer.
The coop is 6'x6'x6' and I leave the door open all the time. I have several nesting boxes, none are in the coop just roosts. Their run is 20 ft wide by 45ft long. 6 ft tall covered with netting to keep out hawks and the occasional possum looking to climb in.
You have a lot more room in your yard than I do. After 2 patios and 2 fenced off raised garden beds, our chickens only have about a 15' x 50' area to range and some of that is taken up by lean-to's, doghouse, canopy, and raised 4x4 dust bath bed for their use. You also have about 6 1/2 times more chickens than I do so that there's more chance for same breeds to break off into sub-groups. With 3 hens now my girls don't have the luxury to break off into little cliques to avoid each other. That may be my problem with the LF/Silkie mix in such a small yard and only zoned for 5 hens, no roos. I wish my LF would be like your GLW and only peck the others away from the feed but the Buff Leg went way too far pulling out the Ameraucana's beard down to skin and started pulling on the Silkies' crests next. I absolutely had to rehome her because there were no other birds for her to chase and scalp! And there were no equal challengers to put her in her place. She was relishing the power she wielded.
If I can get a breeder to ship Breda juveniles rather than hatching eggs in 2015 they will be my last LF experiment as I am running out of options for non-broody gentle-natured egg layers. Our Silkies are terrific egg layers when not broody and so is the Ameraucana. My Buff Leg just started laying again after a broody period and now she's gone. I want to hit my head against a beam or wall or something in frustration!
Brie is about 7 or 8 months old now? Have you weighed her recently? I have read that the Breda hens weigh anywhere from 4-lb to 5-lb. That's a wide range for a smallish breed and wonder what they really weigh?
