I usually don't give treats until the third week, give the chicks digestive system time to settle down and that it works right. I start out with very soft foods(ones that can digest with the saliva and normal stomach acids), scramble eggs is good for protein while they are feathering. My babies are now 3 weeks and they love cooked and mushed sweet potatoes, watermelon, scrambled eggs. I also add grit to their food so they can digest grains and I will start that this week. I will wait a bit longer before giving them scratch, but once they are outside I give them scratch in the evenings to encourage them to roost, and gives them something to look for while scratching the bedding.
Ok!!!! Another question....do they need grit if their outside run is on (florida)sand flooring?? Also, scratch encourages them roost? Im a newbie so im soaking in all this wonderful advise
