I have the bin for the chicks, as well as the lamp and litter, and feeding and drinking waterer, and food. I am going to pick up 3 chicks today. Can someone please help me to know what to do next? I assume I put a layer of litter on the bottom of the bin and turn the light on. I will fill the feeder and and waterer and put them in the bin with the chicks. How much litter should I put on the bottom of the bin? How long do the chicks stay in the bin before putting them outside in the coop? When do I start giving them grit? How old do they have to be before putting apple cider vinegar in the water and what is the ratio? When do I change the type of food they are eating to something else? When do they start laying eggs? Thanks for all the help here!
