I have a 3.5 month old sultan who was just fine last night when she was put in the coop,when I went to let them out this morning everyone came out but her she remained on the roosting bar. I went back out about an hour later to bring them their breakfast and she was still in the coop so I picked her up and it is like she can not hold her head up it is sort of hanging down,I gave her some Nutri-Drench and brought her inside. I checked her over thoroughly,no visible signs of injury,poop is normal,shows little interest in eating and drinking. No raspy breathing,drainage or labored or open beak breathing going on no fever present. I will attach a picture of how she is sitting with her head,it doesn't look like wry neck to me. Her crop is empty, I am just at a loss. Please help this is my daughter's chicken and she is already heartbroken that she isn't doing well
