So I was at my local grocery store the other day, and they were clearing out a bunch of bags of BOSS. I bought several - only $1.50 per 10 lb bag! My pullets love them (of course), but I don't know how many are too many. Want the purdy, shiny feathers, but don't want my girls to get fat! I searched the forums (or fora) for info, but came up wanting. Please forgive me if this is a repeated topic... Anybody have a good rule of thumb for how much/how often? I have 4 pullets who free range for pay of every day and will hopefully start laying soon. TIA!
