layers pellets are just milled and extruded pulverised seed and sorry to say anty.they dont contain anything that isnt found in seed and what the birds pick up themselves, layers pellets are for factory farmed birds . for 6 birds take a sweetcorn tin of mash and a very small amount of water and mix right through till the mash becomes like crumble then add 4 tins of corn or barley and mix again , all my trays are empty so i cant say it is wasted at all i only off advice on what i do tho so each to thier own xx. if i feed sweetcorn i feed it as seed not cooked .as i am not sure about the salt in it ,, if it has any?
