Mocha and 1 of my jumbo hens are extremely thin, and we are picking up feed today I currently feed them Sprout Meat Maker which has 24% protein, should I get corn for them to get some more weight on them? Here is the feed they have at our fleet farm, http://www.mannapro.com/products/poultry/conditioner/ , http://www.mannapro.com/products/poultry/gamebirdshowbird/ , http://www.mannapro.com/products/poultry/harvest-delight-poultry-treat/ , http://www.mannapro.com/products/poultry/oyster-shell/ , and http://www.mannapro.com/products/poultry/poultry-starter/ . Would any of these work including corn? Thanks!!
