Hi! I have 4 new silkie chickens....2 3month old and 2 8 month old. We have a coop and run done for them, but I am scared to put them all outside in this weather. I know the older ones are ready, but I feel like the 3 month old chicks are still not completely feathered. We live in MA and the nights are getting colder! Anyone know silkies that can help? Thanks!
