I am a first time chicken mama. I have 5 chickens. One a long Island Red one Silver Laced wyandotte and three americana's. I bought them all at the same time easter weekend, I think they are about 25 weeks old. I started feeding them lay food from IFA at about 20 weeks, and I let them free range for a couple of hours a few times a week in the evening. I have had one americana laying one a day for about 5 week's now and my Long Island Red has been laying almost one a day for about 4 weeks the others have not laid any eggs yet. I am not sure why. The days are starting to get a little shorter so we have started to put a light on them to keep them moving a little longer but I am not sure how to get them to lay. Any ideas?
