Hi there, our 5 month-old speckled Sussex wouldn’t come out of the coop this morning with the others- moving slowly/sitting and stepping gingerly and standing with her tail tucked far down, nor like usual at all. Her eyes seem clear and no discharge anywhere, but she seems to be clucking strangely too. She’s normally energetic and friendly. Is something wrong?! All the other chickens seem fine and no sign of any issues! They are not laying yet as we don’t have enough light yet in January in New Mexico. These are our first chickens and we raised these 8 birds from chicks. What can be done? Thank you!
