ISO purebred hatching eggs in NH (603)

[Elmbrooker]

I'm looking for some purebred hatching eggs to add to my mixed flock. It seems like craigslist has all dried up and the relay isn't working with someone I had previously reached out to. I want to consider breeds case by case because I want some that will compliment my mixed flock. I do feed organic supplemented by (mostly) organic fruit and vegetable scraps, organic scratch grains, meal worms, etc. I have arsenic in my water so my birds get rainwater or when not available, bottled gallons. I currently have a Wyandotte, Americaunas, Australorps, Sussexes, Rocks, and some Leghorns that were supposed to be Orpingtons. I also keep Guinea fowl, but will be separating mature Guineas from the chickens. I do not have a rooster currently. I am near Concord and prefer to pick up eggs close by if possible. I'm also open to advice from experienced folks. Thanks!
