How often can we feed our chickens sprouts? We have one 18 week old and six 14 week olds. We have been sprouting BOSS, green and brown lentils, and scratch. Is once daily too often? Also is it ok to feed sprouts during the winter--or better to switch to scratch because of the calories and heat generated or feed both? Because of the difference in age we are hopefully going to have 1 hen laying before the rest. Should we continue feeding grower and provide separate oyster shell or switch everyone to layer feed? Thank you.
