Recently, our chickens' gorgeous, thick shelled, orange yolked eggs have been slightly thinner with a much paler yolk. : ( They have a constant supply of oyster shell and get occasional scratch and mealworms, (I recently gave them a forage block which they decimated, lol) but they haven't been able to graze at all recently, due to the newer chickens (assumed) impossibility to round up back into the coop and run. Do you think this is why the yolks are so ugly now? I'm guessing it is mostly the fault of switching feeds - we're back to what I believe we started with (my mom buys the food so I can rarely remember), which is Purina Layena, and am hoping for a positive change. (They absolutely hated the 'new' feed and weren't eating as much). Is there anything else I can do to get those gorgeous eggs and healthier chickens? I am planning on building a little pen for them to pasture in supervised, but in the meantime they're stuck in. (It's a 20ft run, but entirely dirt and sand now). Are supplements, like Manna Pro Egg Maker good for them, or does it have any negative affects? What are the best vegetables to supplement them with? Vitamins, other supplements? Also, what can I give the 'new chickens' to help them with healthy feather growth? 2/3 chickens' feathers are absolutely hideous, dirty and ragged, while my raised-from-chick girls have gorgeous, shiny feathers. Do I just have to wait for them to molt? One poor girl is missing all of her tail feathers.
