I have had my 4 Americana chickens for about 2 weeks now. I bought them from some one that was thinning out her flock. I was told the girls would be laying within the week, but so far no eggs. I looked up some info and looks like the girls have their own time table. The girls are 2 years old. How long will they keep on laying eggs until they are done or until they live their lives? I asked about molting and they went through theirs in July. They have all their feathers.
