I have 9 chicks and its COOLD here in CT,,mine are 7mths old and I'm getting around 6 eggs a day on average. I do change out the water ALOT and use warm..I also feed them a warm mash twice a day which consists of oatmeal, flax, oats, etc , veggies/fruit(I get alot of organic stuff and make a mash as well as their reg feed), and have a light on a timer to come on at 1pm and go off at around 6,,gives them almost 12 hours of light..
