I have one baby silkie all alone. I have 3 other chicks that are almost a month old outside in the coop along with another 7 week old silkie. I plan on keeping the baby silkie (2 days old) inside for about 3 weeks. By that time the temp will match what the average temp is outside. Will the older chicks pick at the new addition at that age? Will I have to wait longer, or just try it and then watch their reactions?
