spinach. My four chickens do not free range, although have a very large run,so I supplement with greens. I gave them collards yesterday and they just picked, ate a few bites. I gave this kale prior and nothing. I know they love spinach, so I took them a huge handful this morning. They go crazy, too funny. I would think the would enjoy all greens. I was hoping for my yolks to orange up a bit. Any other food suggestions? Thanks!
