Ok I bought 4 year old hens 2 weeks ago. Probably not the best move because they looked a bit small and puny but I took them anyway. Ok so I have them on layer feed and they are plowing their way through that. They get grass and clover aplenty, their are fancy scratch grains in with them which is mostly for the rooster. I also provide egg and eggshells ( baked and then crushed fine). They seem like they are still lacking and they are not laying many eggs. Suggestions?
