Keep in mind, Always, ways of acting with our Castilian chicks at birth. In the photo where the Castilians have already hatched, there are always some that have hatched before their siblings, but they are left in the incubator, as their chirping stimulates the birth of the others.
It is important to remove the remains of the egg-shell, to prevent, that they may eat of them, for the reason that they can be their mother's carriers in the shell of the egg of Coccidiosis or Salmonella.
They must be left in the incubator for 24 to 48 hours so that they can reabsorb the yolk (which provides them with enough food), allow the navel to heal—which is very important—and dry off properly.
Chicks can easily become dehydrated if left in the incubator for too long. The yolk allows them to survive for about three days, but survival rates increase if they are provided with food and water within 24 to 48 hours of hatching.
The chicks are usually taken out of the hatchers in the 24 hours following the birth of the first chick. The chicks should be kept in a controlled environment to prevent overheating or cooling.
The temperature should be between 30 and 32 °C (86 and 89.6 °F) with a relative humidity of 70–75%. Adequate ventilation is necessary at all times to provide the chicks with a constant and uniform supply of fresh air.
Already at birth, in their first very important drink of water, we include an anticoccidial agent as a preventive measure against coccidiosis. Coccidiosis and in your case as healing, example Coccivex or any other similar product, during five days, controlling and reviewing the bowel movement of our chicks that are correct.
The drinking water is essential that we change daily, think that they are baby chicks and make bowel movements in the water, this is not healthy for them and is a focus of infection or parasites, to this end we are, we have to control it, it will go in our interest of the good health and growth of our Castilian.
Feed with a feed specific to their age, starting with micro-crumbs, crumbs, and I think keeping chickens, (example Nanta, Biona, etc.) it is important to give a good diet for the development of the first two months, both for the formation of its internal systems, (pulmonary, digestive, blood etc you have more information in the section of Anatomy of the Chicken) and later put all his efforts to the bird, in your skeletal system, and feathers.
I remind you that it is very important, the power the first two monthswith a diet rich in all the necessary components for the formation and growth of our chicken and Spanish, this will prevent malformations caused by lack or deficiencies in the diet.
