They will be six weeks old wednesday. We put them outide in an all wire chicken run with a tarp over most of it. They have a dry place with straw and a 65watt light bulb. This is how we housed my 8 week olds when we got them, but is it okay for my 6 week olds? They are fully feathered. It is raining now, but like I said they have a dry place to go with some heat. Our lowest low in the forcast is about 45, daytime temps in the high 60s and 70s mostly...tomorrow will be a little more chilly so I will leave the light on. Any thoughts??
