depending on the age of your chickens I give mine the dumor chicken scratch with layena crumbles mixed with grit in the blue and gold bag at tractor supply and once a month I give them a dose of packets of electrolytes I get all of at tractor supply and a i get them a bail of straw for their nest and once a week I give them the left over broccoli, green beans, lettuce, cucumbers all finely chopped and just put into there yard where have them and they love it and you will get more eggs then you know what to do with my girls lay on an average 5-7 eggs a day and when I got them they had been mistreated by their former owners my four ducks love this as well but layens crumbles are the best just mix it with your grit and scratch and scoop it out and put into there feeders
I hope this helps it did for us have fun our girls are a joy to watch oh and one more thing get them a mineral block to peck at the enjoy it all total you will spend about 48.00 a month for all this depending on where you live
The chickens LOVE the sweet feed of a flock block but I wish they came with a hanger because mice/rats will eat at them.
