Well, I am not one to feed my chickens things like pancakes, meat, tacos and all the other crazy things people talk about. Mine are on layer pellet, but I do switch brands. Organic pellet is so expensive I usually buy one bag of each. I get an organic veggie delivery to my house and they do get the carrot tops and left over steamed veggies once in a while and I throw the occasional handful of cracked corn or oats. I had a deformed rooster that had issues, so I also have rooster booster vitamins which I add to the hens feed. They don't free range, but I do have a compost area next to their run where they go dig up worms and grub.
She hasn't seemed sick at all but hasn't laid an egg in a while. I figure that is due to the hard molt. All my hens had lice nearly all summer long. I think it's under control now. I'll keep an eye on her! Thanks for the thoughts.
