My chick order of 6 chicks came today. I also have 8 eggs, 6 of which I think are growing, are due to hatch Thurs. by my broody silkie. Could I give my silkie the 6 chicks also? If I can when would the best time to do it. I don't want her to leave her eggs but I don't want the chicks to be to old either. I'm hoping it will work out. Thanks!
