Sounds like it may be a bit cool for them right now. In another week or two they should be fine. I would worry about the night time temps if you don't have a heat lamp. They will feather in a little quicker if the temp is a little below the recomended. (95 for first week, 5 degrees less every week till at room temp). After about 2 weeks they will start staying away from the heat more as their get feathers. Without feathers they can't regulate their body temps well. If they are huddled together in a pile they are too cold but you don't want to overheat them either. They are cute, no idea on the breeds tho.
