I have 2 questions for you guys - 1) Do all hens have to have bright red combs and wattles before they'll start laying? My black cochin has a small light comb and no wattles, yet the store told me she was 10 weeks when I bought her. I bought my girls all at the same time and were told they were the same age. Some of my girls are getting brighter red faces, while others aren't. Do some chickens get bright red faces while others don't when they start laying? 2) We don't have electricity in our coop, and I'd like to give my babies some light at night for a few extra hours. It's getting dark earlier now (7 ish). Do you think those battery powered 'candle' lights (unscented, if they even have them) would be enough light?
