night time temps?

[Aljens Chicks]

I live in S. Calif and have 6 Production reds... Last night was there first night out in the coop. Had 75 wat light in side and it got down to 49 inside. They have 4" of bedding on the floor and food and water. Coop is 4'X6' and they are 6weeks old. They have real close to all there feathers. Are they ok????

They should be fine.
