too young to go outside?

[stumble_n_mumble]

hey guys i have 1 silkie and 1 runner that are 7 weeks old. 7 silkies that are 4 weeks old one canadian gosling thats about a week old. they are all outside now because its 80 degrees and they love it. i have a insulated coop with them that has a plexiglass door that slides closed. if they all sleep together in their should they be warm enough for the temperature to drop into the 50's??

The duck should be fine, Is the silkie fully feathered?

the silkie thats 7 weeks old is feathered but the other guys are.... not really. but the 7 week old silkie is the same size as the little ones but with a ton of feathers.
