Title says it all. They've been living in the green house for a few hours only, and a cold front comes in! Low was 70 last night, and its suppose to be 50 tonight.. Ugh I really wanted to start keeping them outside. This site, which seems nice. Wish I would have found it sooner. Says, optimum temp is 66 at 21 days, 59 at 28 days. They're 25 days. I'm not sure what optimum means but I'm not sure if 1. they'd like it, 2. they'd be safe http://www.duckhealth.com/housmngt.html I'm pretty sure they'd be safe since they get hot in the 70s but I dunno. They're definitely getting feathers, and have at least partially functional oil glands since they swim so much. Sometimes they come out of water looking dry. So, should I bring them back in for the next two nights? After that its suppose to be lows in the 60s. I hate the idea of bringing them in again. It has been such a nice half day just keeping an eye on them. And they seem to love it too. Its actually been hard to get them out, and I've left the door open, and even took food away to temp them to explore and eat w me wild style..
