My 5 chicks that I hatched out are two weeks old today. We still have them under a light and inside the house. The 3 Black Andalusian are getting VERY big, I think I will have to seperate them out soon. My questions is?? How long do I have to keep them under a light and when is the appropriate time to introduce them to the rest of the flock. I have 15 more eggs (white leghorn, black andalusian and old english whites) in the incubator and due to hatch out on Aug 15th.
