Hi, I'm new, haven't gotten my chickens yet. Planning for Spring. I am so excited! I plan to only leave food out during the day, but have water both inside and out. I'm not sure how much to feed. How do I know how much a chicken eats? I plan to have six hens but I may get more to start with. I am planning on having standard size chickens not bantams. The ones I picked are Australorps, Wyandottes, RIRs, Orphingtons, Speckled Sussex, and Delaware.Do these different kinds of chicken eat more/less or all about the same?
