I have little solar powered lights that come on at dusk and then fade off.... still nada. They arent super bright, but I was under the impression they dont have to be. Been using them for about 4 weeks.
EEs have a reputation for being slow to start laying and BRs have a reputation for starting early. However, every chicken is different and some take a long time to get going and some start very young, regardless of breed. Be patient. One of mine didn't start laying until 36 weeks.
I have a chicken,....we will call "it" Pat. I will wait for her to lay eggs as long as it takes. Until He crows. Then the waiting is over. I have two younger chickens that are not really laying yet. I got them from Craigslist, and they are lovely birds, but I don't know their exact age. It will happen..... Very exciting when you start getting the eggs!
