The BSL chickens that we have are fairly unsocial birds. Granted we did get them at about 18 weeks. They often hide in the back corner of our large run, away from us. When in the coop, they have been caught pecking feathers off other chickens, enough to make the others bleed. They do lay very nice eggs and are pretty birds. Large bodied with shiny black feathers and a brown to copper brown chest and neck area.
