We added a light to the coop that I turn on around 5 am. I would LOVE to see some eggs. How long does it usually take for the light to have an affect? I have one hen that laid up until October then quit (serama) and the rest are D'uccles and an EE that are 26/27 weeks old. The D'uccles had bright red combs over a month ago and started squatting about 2-3 weeks ago. I figure the EE isn't quite ready yet. I also have a Cuckoo Maran, Golden Lakenvelder and Cochins that are 19/20 weeks old.
