We have a Roo and 2 girls that now spend the day running all over the place picking and a peckin. Our yard is big and they have favorite spots but for the most part cruise then nap then cruise some more. I feed them 21% laying mash and throw in a handful of boss and have a pan of scratch out for them. I have been concerned that they dont devourer it by any means. I have learned to leave the feed down for them only for 10 minutes and they come running when i put it down a couple hours later and go at it for a bit then get back to their cruise pickin and peckin. They get some mackerel every day and yogart which they love but it seems like they show just a little interest in the "real" stuff. They lay predictably, 2-3 days on 1 day off. look fat and have plenty of energy. Do chickens get ample nutrient when they range?
