Hi! One of my Buffs went brood 20 days ago and she has 9 eggs under her. I've heard chirping and 3 eggs are beginning to hatch. She has been a VERY GOOD momma and has only been off the nest twice in the past 20 days. My question is: I'm in Richmond, VA where our weather is constantly changing. The high today should be 45 but we have a north wind screaming across the fields. Over the next 7 days the nightly lows will fluctuate between 25 - 43 and the day highs should be between 46 and 62 with rain and snow in the forecast around the 17th. The temperature in the coop is 42 right now. I'm wondering if I should put a brood lamp in the coop for the babies to supplement momma. She is currently in a nest box about 12 inches off the ground. I'm concerned the babies may get out of the nest box and get back to momma. What do you think? Thanks for your feedback.
