Hello everybody... I was out feeding everyone some treats and noticed a really foul odor...I checked all of them immediately and realized it was my black cochin's rear end. Her feathers have matted together and her vent is red on one side and there was sticky yellow poop on and under her vent. Is this Vent Gleet? How do I treat this? I thought I read somewhere NO antibiotics. Gonna need help with this one. I have no real history on her. I was told when I bought her at a farm swap (lesson learned on that one!)that she was a great layer...that was the middle of January and I have yet to see a egg from her. She is a bit stand-offish. She stays behind everyone, last to the feeder, last to drink, won't roost on the roosting bar...she stays on top of a nesting box closer to the floor. However, she is quick to peck at the younger pullets at the feeder and waterer. Not sure if her behavior reveals anything or not. She gets Bragg's ACV in her water, Epsom Salts in her pellets, and evening mash usually consisting of white or brown rice, butter milk or yogurt, spinach or romaine lettuce, wheat bran, fresh garlic and olive oil and strawberries, apples or grapes. Morning treats are usually greens or fruit. I keep Diamatious Earth and Seven Dust in the coup and where they take dust baths. Thank you for any help you can offer!!
