I finished the coop today and moved my almost 7 week old girls out there around 6 PM. We went out to dinner and the movies and I just got back and checked on them at about 10:30 PM. It was a cool and rainy afternoon and the temperature outside right now is about 60. It will probably be in the low to mid 50s by morning. Three of the 8 were on one of the roosts and the other five were on the shelf over the nesting boxes, sort of huddled in the corner, so I spent the next 15 minutes setting up a heat lamp for them. Am I a wimp? Overprotective mother?
