We are learning about life cycle and incubated chicken eggs. They take 3 weeks to grow inside the eggs. We were able to candle the eggs around day 14 to check on the development. If we look closely you can see the chicken moving inside the egg on the video. Then on day 21 as expected they began to hatch. After 1 long day and night 13 chickens hatched. They are doing fine and growing everyday. We will keep them for 1 week and then we will send them back to live on the farm.
