So I have this 5 month old hen. Her partner died of Marek's recently and now she is sick. She doesn't show symptoms sane as the other chicken that had mareks. Her face is swollen around the eyes and her comb is pale AF. There have also been black spots on her comb for more than a week now. (The pictures don't clearly show the black spots as they are only on the left side of comb) She looks in so much pain. She looks like she is crying. I want to cry out loud every time I see her. In just two days I lost my grandfather and the other chicken I had and one little chick I had(mareks I think). I have given her 250mg tetracycline antibiotic that fights bacterial infections. I mixed one quarter tablet in water and she drank a few drops. I also put two little pieces of the tablet in her mouth. I can't go to a vet or anything out of home (the house is full and busyy In mourning for my grandpa) but you can suggest medicines as I might have them at home. is it some kind of pox? Or is it Marek s? Help!!!!Quickkkkk!!!
