I have been going on a worm hunt (frequently several a day), finding and digging up worms and slugs and grubs to feed my chicks. They were about 4 weeks when we got them and now they are about 8-9 weeks. Will feeding them from my hand (the protein snacks) keep them from learning to find them on their own (We have kept them in a crate until we could integrate them in with the adult chickens). We have 4 adult hens and 3 chicks not related. We are still feeding them pullet mash and millet seeds and oyster shells. We've never had chickens before and are in the dark a lot concerning their care.
