I got my girls back in February. We have 3 that are 10 weeks old and 2 that are 11 weeks old. The temps are getting down to the high 30's, low 40's at night. Do you think that they will be OK moving outside now? They are getting too big for their brooder, but they have feathers now and their combs are starting to really come in. If I do put them out, do you think I need to put the brooder lamp out? I have seem some bad fires on the internet from the lamps so I am a little nervous about that but otherwise, I am so ready to get them outside. Thanks!
