I would like to add baking soda to my laying hens diet this summer. Which I have read is commonly done on commercial farms to increase calcium absorption. But the weather will be 100-120 degrees and the chickens need ectrolytes added to the water. Can they be given baking soda and electrolytes? The article I read it from said to use either or but not if you could use both. Also will baking soda harm chicks eating the older hens feed?
