I have a girl that is about 1.5 years old if I was told correctly when I bought chickens about 5 months ago, he stated they were a year old.I do not know what type of chicken they are. The molting research seem to be on cue with autumn/winter and age and I will ramp up protein for them... I live norht of Atlanta GA if that makes a difference. I am concerned about the little white dots on her as in the picture, I use DE-food grade but very little, they bathe in ashes from fire place (very little paper used no toxic wood) mixed with dirt and DE-food grade. I also spread the ashes in the outside run/ dirt floor with some oat hay which is also in the coop which s i cleaned weekly. Just want to keep my girls healthy as possible for a not so educated chickguirl. I only have three but they are good layers 2-3 eggs on most days even after getting cold here they are still going strong. I also give them ACV with mother in the water -just started that, laying mash (lot of and they scatter that everywhere) and treats every day. Treats consist (depending of what is available) of bread, salad, sunflower seeds, some nuts occasionally, beans, squash and they are about to feast on pumpkin and they get some fruit from time to time oh and yogurt as as I have found two broken mostly eaten eggs, they now have a fake eggs so hopefully that will help...all of this I have learned right here!! and I am so grateful for this information as they would probably have already met the chicken god...Thanks to All.... love this site have learned much and learning more as I go, thanks to all who so graciously chime in. Much appreciated!!
