I give to my girls and boys all the time. I can always tell when the wild birds eat them because they leave the shells behind. I have a couple of 8 week old chick that are now eating with the hens and roos, so they now have access to them as I include it in the mix of their food. They are all free range, I pull weeds and toss them to the chickens because area they free range they have demolished all the greens if there were ever any. I want to plant some thing hardy that will cover the dirt quickly but that will also handle the scratching of chickens and be beneficial for them too if they were to eat it. I tried fodder over the winter a few times and it worked out nicely, but I just don't have trays to anymore. I had bout a seed starting kit, the kind that comes with the jiffy pellets, and poked holes in the bottom of the trays, but the trays didn't hold up very long and figured it would be too expensive having to by the trays all the time. If I could find something sturdier, then I would do it again, but I don't want them too big either. Any ideas?
