Gather the shells and clean up the coop, likewise, do not feed the dirtied eggs to chickens. Introducing the chicken to the egg will start them developing a taste for it that could start the habit. Chicken could also start pecking at the eggs if they are bored. Keep them busy by hanging vegetable scraps tied to a string for them to peck. Corn feed is mixed with other seeds and the seed mixed to the corn does not differ much from one manufacturer to the other. The other type is pellets. Pellets have three categories. First is the starter mash or layer mash, the second is the crumbled pellets that are recommended for feeding the pullets and the third is the pellets. Chickens that are not over stressed are more resistant to infections. For this the chickens must not be disturbed, if that cannot be avoided, prevent disturbances to the least possible. Chickens are naturally evasive to contact from those that it is not familiar with, even unfamiliar human scent. Except for scheduled management and maintenance, the supply of water and feed must not be interrupted. Mix vitamins and minerals into the water to insure that the chicks grow healthy and to boost their resistance to diseases. This is especially important during the first week. For food, you can mix crumbs to the starter mash that you feed the chicks. Taking care of the chicks will require you to follow manufacturer's instructions for ratio and proportions of vitamins, minerals, and crumbs that you mix with their food. Normally, healthy foraging chickens will swallow small pebbles. They know what to select and what is good for them. However if the chicken is not let out of the coop for long periods, they miss this digestion aids. Another thing that is common to most animals is to eat a particular grass for a particular illness. Starting from a starter mash, it will need crumbles and then pellets. This is no cause for worry though as the feed is basically made of the same mixtures and components, the differences accounts for the degree of coarseness of the milling only. As the pullets grow, it will eat just about anything that catches its interest.
