in 2 weeks. It's been years and years since I started with chicks. How long do they stay under a lamp? What temps do they need? These are a mixed group of large layer pullets. They will be 2 days old when I get them. Since it still gets very cold at night around here, they will be in a large tote in my house for the first week or so even with a heat lamp. Run the basics by me again please??????????
