Bovan Browns. Bought 70, they're down to 45% production at 14 months from point of lay. Look terrible, lots of missing feathers and really red butts. I have to toss 5 or 6 eggs of what I do get due to poor quality shells that break when I wash then (gently) They get 17% pellets, scratch and seed, oyster shell, ground flax seeds, fresh greens from the produce culls, always clean fresh water. Very flighty birds; no predators. No mites. Clean house. I'd appreciate any comments because I'm about to give them away to anyone who wants a few chickens wandering around and a few eggs... I've kept chickens for years, had hundreds of them but never had such a rum flock.
