Then I have to ask again who/what is going to care for this chick if it hatches? It will need a mother hen or it will have to be brooded with a light to keep it warm and a box or dog crate or something for a safe location, shavings for bedding, food and water. It will have no siblings for company/warmth and your other chickens will not care for it and without a mom to defend it, may even kill it. At any rate, if your plan is to dump it at a day old into the pen with the older flock, that is almost certainly a death sentence for a hatchling.dont have a rooste... wait i just realized what you ment however they arent even laying yet
