I want to get 3 - 4 hens (I think 2 ameraucana and 2 buff orpingtons). So, for food... I'm supposed to always have layer pellets in the feeder, and I can scatter a few handfuls of scratch on the ground? Or, is it better to mix everything together? I saw one person post that they also mix wild bird seed in with their layer pellets. Is that a good idea? And I thought I would just move the compost pile so that it was closer to the chicken coop, so they can eat scraps and "mix" it for me when I let them out. But, will they get too many scraps that way and get fat? How much feed to you think I'll go through a month? (About how much will it end up costing, for just 4 chickens)? It is usually about 1/3 pound of food a day, each, right? I'm just getting mixed up with all the choices, and how much they should eat of each thing.
