My chicks are now a week and a half old. My have they grown. There are seven of them and they go through about a quart of food every day. They are so friendly too. We have been handling them a lot. They like to stand on my fingers and like to come over when I put out my hand. They are such sweeties. The ladies are also getting some good feathers. My Cochin has been slower to mature though. Most have wing, tail, and are starting to get some upper-wing/ lower-neck feathers. They are on medicated chick feed, and have nearly gone through a bag. They should probably brood for six weeks. When can I start giving them grit and different food (grower and scraps)? At this age will they still enjoy hard boiled eggs? What food will they need grit for?
