I just added 3 Australope pullets to my layers. They were reportedly 16 weeks old so no laying yet. One of them was much lighter in weight than the others and had a white comb (not fully developed) and white face where the others were bright red. I also noticed that her feet were deformed - toes going every which way. After only having her for 5 days, I found her laying on her side in the grass with the others pecking at her. I isolated her, fed and watered her and she seemed to rally. But, this morn she was dead in the coop. Im concerned that I might have gotten a diseased chicken. The 2 others seem very lively and fine as are my other chickens. Im pretty new to chickens, so if you have any advice, Im all ears!
