The food should contain enough protein, vitamins and minerals for sustained growth over the next several weeks. Once in the brooder the chick should be introduced to water and feed and placed under the light or brooder plate. Once the hatched chick is dry and fluffed up they can safely be moved to a brooder area. If you have a broody doing the job she will have them up and moving fairly quickly. If your chicks are in the incubator then they can stay there for up to 48 hours after hatching. Hatching is usually accomplished within eighteen hours but can drag on a little. Embryo starts to breathe air and becomes a chick. Day 20: The Yolk sac is absorbed and umbilicus now closed.Day 19: Yolk sac moving into the body and embryo now occupies all the space except the air cell.If your eggs are in the incubator this is lockdown day. Yolk sac still outside the body and their head is under their right wing. Day 18: They are almost fully grown now.Day 17: Egg white is now absorbed and their head is between their legs.Day 16: They are now completely feathered.Day 14: Head turns to pipping position.Day 13: Leg scales start to appear and they have light covering of feathers over their body.Day 10: Egg teeth and claws are formed.Day 9: Claws begin to develop and embryo now looks bird-like.Day 8: Feather follicles start to appear and ear canals open.Day 6: Beak starts to form and voluntary movement starts.Day 5: Elbows and knees develop and their eyes are visible whilst candling. Day 3: Heart starts to beat and blood vessels are visible.Day 2: Tissue development starts as does blood circulation.Day 1: Development of the germinal disk begins.However for those who like a chart to go by one is laid out below – the chart gives the highlights of each day’s development of the chick. The above video shows the development of the chick very nicely. If the sperm does not implant itself here the egg will be sterile. The egg only remains in the infundibulum for around fifteen minutes so it is a small window of opportunity. Once the hen and rooster have mated the sperm will begin its long journey to fertilize the egg.įertilization occurs in the infundibulum – the part of the reproductive tract that follows on from the ovary. The rooster will evert his cloaca allowing his papilla to deposit sperm inside the hen’s body.Īll of this takes less than a minute and when they are done she will shake out her feathers and go about her business as usual. At this point she will evert her cloaca ready to receive the sperm. The hen has squatted in submission and lifts her tail end up to meet him. He will mount the hen from the rear using his beak to hang onto her head or neck feathers and will use his feet and claws to hang onto her. The mating is a brief and precarious thing. If she is interested she will squat in submission, if not she will walk away or ignore him. He will drop one wing to the ground and shuffle around the hen. He will perform the courtship dance to indicate his interest. The rooster that wins out will usually be the healthiest and best of the bunch. He will indicate the food by picking it up and dropping it repeatedly until the hen comes to investigate. Mating behavior involves rituals such as tidbitting where the rooster will find something interesting and start calling the hens. All of these things give her some idea of the health of the rooster, his ability to find food and whether or not he will make a good flock leader. They consider things like appearance, attentiveness and food finding. However hens are quite calculating in their selection of a mate. Usually roosters will try to court the ladies and put themselves forward as the best rooster for the position of flock husband. The first stage of the chicken life cycle is the egg getting fertilized. Life Cycle Of A Chicken: Stage 1: Egg Fertilization
