Thanks for the response.
They are just over a year old. I have been feeding them organic layer feed 16% but have also been supplementing with organic chick starter 19% for the higher protein. I can’t seem to find higher protein in any layer feed organic or not. I also try to give them 2 to 3 boiled eggs or sardines in water with the chick starter mashed into it to also increase their protein as well as dried mealworms as I have had issues with feather picking. I am not sure how well it is working. My Leghorns are the biggest culprits followed by my Orpington but I even find the ones that get picked (Easter egger and Barred Rock) picking at one another. It tends to happen when they are dusting bathing more than any other time and they don’t tend to eat the feathers as I have witnessed the behavior. There are also feathers in the areas they dust bathe that are edible but seem to be left. I have even put blinders on the three but feathers still went missing and as the weather got hotter I felt the blinders were not appropriate.
I do have a garden and feed them some of the produce and herbs that I know is ok. I have not been sure about weeds, except chickweed in the winter, to know if I would be giving them something bad/poisonous.
Sorry for the long response...it has just been a bit frustrating dealing with numerous issues and never feeling like I am getting it right even though I put a lot of time and effort into caring for my chickens.
