This is my first year with chickens and so I am learning as I go. It has not been the easiest learning experience, but I have grown to love my chickens dearly and they are worth it to me. My poor rooster came down with MG this past December. He did not see a vet, but presented first with rattling breathing with his mouth open and clear nasal discharge. I added ACV, garlic, cayenne pepper, and probiotics to his water (at different times of course), with little improvement.. He then developed bubbles in his eyes and it was then that I was finally able to diagnose him with MG. He never experienced sinus swelling. I treated him and his coopmate with denegaurd, although I cannot remember the dose or dosing schedule that I used, but I found it on this forum some time in January or February. He seemed to be feeling better and the eye and nasal discharge stopped. He continued to breath with his mouth open when stressed and still seems uncomfortable when you touch his throat-he opens his mouth to breath when it is touched. He has been suffering from depluming mites and it took me a long time to be able to figure out what they were and how to treat them. I started treating my whole flock with ivermectin pour on once every 7-12 days and have given three treatments so far. I plan to do two more treatments as suggested in another post. From what I understand he will not regrow his broken and damaged feathers until he molts, but I hope that it is helping because it has spread to my hens at this point. He is a brahma so the first place I noticed an issue was in the feathers on his feet. The skin at the base of the feathers started to turn bright red and some of the feathers were growing out damaged and a few had super thick quills filled with a scabby like material. I initially thought that this was causing him pain so I cleaned and soaked his feet in epsom salts, tried to pull a few of the affected feathers and trimmed some so that they would not effect him when he walked. He has been limping for a few months now and I had thought that it was because of his feet. I recently was near by to him and heard a clicking/grinding noise while he walked and realized that he must be experiencing some kind of MG related joint issues. I have heard that some people recommend culling MG infected birds, but he is the sweetest rooster I really don't want to lose him. I also really don't want him to be uncomfortable and in pain though so I am looking for some advice as to what I should do for him. Should I be treating him again with denegaurd? If so, can someone please tell me the correct dose/dosing schedule so that I know I am treating him correctly? Do all of my hens have MG now? Should I be treating everyone? I am at a loss for what to do next and I feel badly for him. He looks like hell, missing feathers all around his neck and his skin is very red and irritated. The noises from his joints concern me most, will this get better? Thank you for any and all advice as to how to make him feel better/recover.
