Smart idea about the "Junko's" my friend!I have a variety of birds especially now with two feet of snow on the ground. I feed peanuts, sunflower and safflower. Also suet this time of year. Also buy "cheap seed" at the grocery store to throw on the ground. The Junko's are greatful and it helps keep sparrows off the more expensive feed.
We've been feeding our son's chickens fatty stuff in this wicked cold.
