I have four hens (all different breeds) that are free range yearlong. Now that all of our beautiful snow has melted, they're foraging among the frozen leaves & grass for food, and also eating the dog's dry food (with him staring on in disgust). I've started giving them a handful of black sunflower seeds each morning when I let them out before I go to work. They really aren't getting any other treats than that, although I'll occasionally give them various table scraps or canned dog food mixed with canned corn, but that's rare. One is currently laying an egg every day or every couple of days. I've been supplying them with 20% protein crumbles. The store also has 16% crumbles. I've felt that the higher protein will keep them from attacking each other & their eggs, but I don't know if they actually need the higher protein since they're feasting on dry dog food & whatever else is in my back yard. Do you guys think that they'll do just fine on 16% protein crumbles? Once the bugs come back in the spring, will the higher protein deter them from eating the bugs?
