I am a first time chicken owner. I have 5 chickens ,buffs and americanas. For the first time I cracked an egg that was laid this morning and there is a very large red streak in the yolk area. I don’t have any roosters, they get food grade DE in their food and their dust bath area. They have an coop and an enclosed area of 20 x 20. They are let out to roam at 7 am until dusk which now is about 630pm. I have attached a picture for clarity. Thank you for any help P.s. I do have wild turkey’s in the area ?
