In addition to the ckicken not laying good lately, I just noticed that a couple of the chickens have kind of pale, not bright red combs & wattles. They are eating and drinking fine. I clean their water every day and make sure their feed is good and fresh. They get treats such as oats, sunflower seeds and I started giving them a wee bit if scratch again. Also they get stuff from the garden such as lettuce, carrots, greens, peas, NO potatoes. I have given them a grapefruit cut in half once in awhile until I read that citrus was not good for them. they are 8 months old. They started laying at 17 weeks old.
