Does anyone offer salt free-choice for their birds? Our layers our free range, have a hopper of layer mash indoors, a scoop of scratch grain tossed in the hay daily and thrown outdoors as well. Their outdoor fenced area is looking a little sad these days as nothing's growing yet (heck we just got more snow today!). And now, for the first time I've been noticing some feather picking/eating. Since the layer mash is only a portion of their diet, I'm not sure they're getting enough salt, and I've seen a few recommendations on giving chickens salt free-choice which I'd like to do. As well, are black-oil sunflower seeds sufficient for upping the protein?
