Hi guys! I was wondering if I should add a light into the coop? My chickens are about 6-7 weeks old and I live in northern New Jersey. I have 4 Arucanas and 2 silkies. The temps at night really range from 66-40 degrees Fahrenheit. Should I add a light into the coop for the colder days? Tonight is there first night out and it's going to drop from 81 to 64. Thanks in advanced!
