Hi! I will be getting my chicks the week of July 5th. Lavender Orpington, Buff Orpington, Barred Plymouth Rock, Golden Laced Wyandotte, Blue Ameraucana. I ordered all females because I am not allowed roosters where I live. I am getting everything I need for the brooder. My question is on the heat lamp/heat plate. Which is the best? How do I change the temp for when I start reducing it every week? How do I place it in the brooder, high/low? Thank you so much!
