This sounds kind of dumb, but I've never ever bought chicks this early in the year before, I almost always wait til May or even June, when weather is much warmer, or, most of the time our chicks are with their mom and I don't have to worry about them. We have 8 four week old chicks. They are still in the house. Normally they would go into a pen in the barn by now, or certainly by five or six weeks, but the long range forecast for April through the beginning of May at least, calls for day time temps in the mid sixties, with an occasional 70 & degree day, and night time temps in the forties. I think they would probably be fine in mid sixty temperatures, but I am thinking I should still bring them in at night? Or will they be ok if they huddle together?? They are rare breed chicks so I am a little more anxious about them. They are also growing like mad and we are running out of room, so all the more reason why I'm anxious to get them into a bigger pen out there. Thoughts?
