Hello everyone. When I woke the morning to check on little lady I saw that her tail butt area is a grayish white. Is this normal? She gets mists for 3 minutes, 30 minutes before light go on and and 3 minutes after lights go off half hour later. She also gets a 1 minute mist at 1am since I live in a dry area. The fogger goes in at 2-5am. She gets feed daily with calcium and 2 times a month with the d3 calcium. She has a lay bin since I’m not sure when she will start to lay.
