I put my babies outside in their coup for the first time at night tonight and they are not happy. We have been putting them out there for a few hours during the day for several days and they loved it. We decided since the weather is beautiful down here in Houston it was time to let them stay out all night, although I do have the heat lamp out there for them too. But once the sun starting setting they were all lined up at the run gate cheeping like crazy. We shuffled them up in the coup, turned on the heat lamp and closed it up nice and secure but they have been cheeping non stop for 2 hours now. How long does it take them to get used to their night time lodgings?
