My pullets hatched on June 14th, so they are getting close to laying age. Since the days are getting shorter, should I put a light in their coop to extend the day so they will lay? (sort of poetic, dontcha think?) And nest boxes, should I wait until they start to lay or put it in before they start? I have a mixed flock, not really sure what they all are, though I do have 3 Polish. I think a couple are Blue Andalusians and a couple more look just like them only they are splash. I think another one is a Leghorn, maybe a couple are EE. So, add the nest boxes soon or wait it out until they decide to lay? Light or not?
