I love sunflowers and planted a bunch of different kinds- in addition to all that the birds planted for me. I assumed the chickens would love them. As fall came, I gave the girls a few heads. They enjoyed them, but didn't go crazy for them. I ended up hanging them in my basement to dry and figured I'd give them to the wild birds. Last week I saw them hanging down there and decided to bring one up for the chickens. Oh my gosh- they went crazy!! They absolutely loved it, when I went out a little later the entire flower was gone-no evidence left! I think they were spoiled when there was no snow on the ground and they had their pick of goodies! In the middle of winter it turned out to be a wonderful treat! I don't think it much matter which you plant as long as they have seeds!
