I'm trying to calculate feed cost on baby calves. As their status (on pasture, on milk sup, or sold)changes their diet changes. while on milk supplement, they also get starter grain and hay when their status changes they may just be on grass. We feed a continuous amount of hay and grain so we just average cost over all of them. Trying to sort cost by the day their status changed, which could be 1 or 10 head and if they get stepped back down a level. I can get the amount to work right but it always over all calves and sorting criteria isn't working for me. any videos or sujestions would help. Thanks
