We bought 7 Coturnix (all hens) 6 weeks ago. Had them in the brooder in the garage with artificial light for 4 weeks. Moved them outside in a house and pen 2 weeks ago. It's 60 degrees average daytime temps, night time lows around 35 average. April in New Jersey - plenty of daylight, plenty of water - nipple gravity waterer, feeding Blue Seal Gamebird Starter - 22% protein. I have a solar garden spotlight aimed at the house, mainly to keep predators away, but it is providing more hours of light. Only 1 hen is laying. I get only 1 egg per day. Any ideas why? I've read about changes affecting them - we added the nipple waterer last week, and raised the house up onto a second set of blocks the other day. Is that enough change to cause them not to lay? If so, why is the one hen consistently laying?
