HI all, I'm currently raising my first flock - I have six gold star hens that are 6 months old. I have been letting them free range since they were big enough to fend off the barn cats and so far we have had no problems. I went with the gold stars because I was told by the hatchery that they are a hardy breed that can withstand our Minnesota winters. My question is, how cold is too cold to let them out to roam? I know they probably aren't finding much by the way of bugs and things to eat, but they still love to forage and I hate to keep them cooped up 24/7. But two days ago we had a really cold, bitter day and four of the six got "stuck" at the neighbors because, I am assuming, they got too cold. We had to go over and get them and carry them home. The two that did come back were acting strange and I had to pick them up and put them back in the barn too. This was in the evening after they'd been out all day, they are always back here at dusk and put themselves in their coop by nightfall. I won't let them out if it's going to be too cold for them - but I don't want to keep them enclosed in a tiny coop 24/7 either. So I'm wondering, how cold is too cold? It's supposed to be in the 30's today so I'm going to let them out. Monday it was only in the single digits and it was the first really cold day they've ever seen.
