Does it matter? I am looking at some sites to buy them and some are offered roasted/unhulled and some are unroasted w/hull. Why isn't there just plain ole pumpkin seeds? Does anyone have a good place/site to buy and can offer advice on a reasonable price to pay? I'd like to start giving these to my chickens periodically (once a month maybe?) I wonder how many lbs I should give at a time--I have 50 chickens. Anyone?
