It is about 65 degrees Fahrenheit average throughout the day and about 50 degrees at night. I have 6 production red (5 months old), 1 EE (2 years old) and 3 Leghorns (2 yrs old). I get about 1 brown egg, 2 white eggs and 1 green egg every two-three days. Is this still acceptable? Or are the chickens not laying well?
