I have 4 hens, 1 rooster, and 3 pullets in my flock. Yesterday I lost one hen. She appeared to be molting (no eggs, pale comb, loss of feathers), but she went down hill pretty quickly. This made me wonder if I am feeding them all that they need. Even though I now only have 4 hens, I am only getting 2 eggs. They are around 16 months old. I have not had an egg from one hen in several months (unless I got her confused with her twin that recently died). if that was the case, it has been about a month or so... They seem healthy... They free range, and live near the barn, so they find lots of goodies. They also eat birdseed from the front yard. But I provide them with chick starter, oats for breakfast, and oyster shell. They also get treats such as fruit and bread. They even eat cat food when they beat the cats to it. Is there anything else I need to be giving them? I once saw a thread on here that listed what human food chickens could have, but I would just like to know what else I should be feeding to keep them as healthy as I can.
