I have not noticed anything in my birds that would point to Respitory but im new to this and probably wouldnt know if it hit me. My coop is drafty and I do not have a light in it and we have added new birds about 4 days ago and they have been fighting regularly. I have only 2 Hens that lay funny eggs but about 15 with the black spots Unfortunatly I have no way to post a picture but I could identify it if I saw it. To send a hen to the State Lab should it be alive or dead??
