So I have had my chickens for about 2 months now, I have 6 and so far we are enjoying it and actually getting 3 eggs a day. Some of the chickens haven't matured yet . Though it should be soon. It's kinda like watching water boil however. Anyway, I know that birds need grit to digest their food. I have read that if you are feeding them a commerical layer feed that grit is not necessary, however, I am also feeding them scraps including veggies, fruit and I have just purchased some scratch. I am sure that with the scratch I will need grit, the question I have is how often do I need to give them the grit?
