I had my chickens (20 weeks) on Flock Raiser. I went to the feed store to buy a bag of Layena but they were all out and gave me Nutrina Layer. My issue is they look like they are getting a little skinnier. I have a white rock (so i can definitely tell on her) and she was pretty big but not so much now. I know that a fat chicken doesn't mean a healthy chicken but...just makes me nervous. However, I have noticed that since I started using this feed their combs/wattles are all turning red and growing! They are all acting really healthy and happy. By the way...the only thing their laying right now are big plies of healthy looking poo . So I am really confused. Could the Flock Raiser have a higher fat content? Should I go back to the flock raiser? Is flock raiser sufficient for egg layers or is Layena better? Are they all turning anorexic lol?
