i wave a 3 year old Sexlink that yesterday and today she is not eating. She lays around a lot. Tonight I gave everyone some salad and she stood in it but didn't eat any and didn't move. Her comb on her head is laying over and has a blueish tent to it. I have felt her belly to see if she has an egg stuck. But it feels fine. She hasn't laid an egg since last September when she started a molt. Can anyone help me determine what might be wrong with her and what to do for her to make her well again?
