Hi there - I just got some more EEs today, and they're almost 8 weeks old. They're pretty well feathered out, but I'm sure they're not 100% there. I've got them isolated from my existing flock and will keep them there for the next month. Here's my question: the house in my isolated run is definitely not draft free, and it's going to be in the mid- to upper-twenties tonight without any wind. Will they do all right in there? Should I put a 250-watt heat lamp in there with them? Should I put a tarp over their house at night? My other option is to put them inside in my workshop every night for the next month until they're ready to join my current flock in the comfy coop, but that doesn't sound like much fun for me or them. What do you think? Any suggestions? Thanks in advance for your help.
