They arrived from the breeder at the end of May, 6 pullets (3 hatched out last November and 3 hatched March 20). One of the young Cream Legbars had bubbles coming out of her nose on arrival. Being a newbie I thought, well that ain't good! (It was a clear, runny discharge the whole time she was sick) I was giving probiotics/electrolytes for the stressful travel day. They had a long day but not continuous travel, since they had a nice shady rest in the middle of the day - came from 4 hours away. I contacted the breeder by the end of the first week and she said that was strange and to give them the probiotics/electrolytes and said it was probably from stress. Shortly after I had contacted her the other 2 hatched on March 20 came down sick. They developed runny noses (that had a thicker discharge than the CL and some crustiness) and eventually a cough/sneeze. But all three remained alert and active. After several weeks of this I new it was more serious (hindsight I would have done a lot different, mind you) so I took the sickest little to the vet. He did a bunch of swabs and a blood test and after having to come back a second day (over and hour round trip to vet!) we fed ex'd it to Puyallup for testing. Both the swab (PCR - culture) and the blood test were positive for MG. I let the breeder know this and she said it's not in her flock and would take no responsibility at all for these birds. The vet said it was unlikely they picked it up on the way (it was a warm, dry day FWIW). Stress could have brought out something they had in their systems. The youngest 2 were Marans and they looked pathetic compared to my other Marans who are only 5 days older but were much bigger, vigorously healthy and with shiny feathers. I was very careful who I bought birds from getting started this spring and I did a lot of research - like almost a year's worth, so it was very frustrating to go through this. The vet said that now the FDA has no withdrawal time for meat and eggs if you give antibiotics, meaning you should not eat the bird or eggs for life of the bird. Of course, most backyard chicken keepers may not adhere to this. After much deliberation I decided to try antibiotics and see if they improved - I tried Duramycin for 9 days with no change. A couple of days later we culled the sick ones. The three older ones never showed signs of illness despite sharing the tractor with the sickies, food and water, etc.
Also, I asked the breeder to test her flock and she basically made accusations at me but eventually said they would test. Never heard back from her. My husband wants me to have no further contact with them.
So, that's it in a nutshell.
Aw, so here we go, thanks for coming forward on the symptoms and YES you did have nasal dischage.
MG, yes I have had that bad boy several times, and yes it is passed through the egg, and yes I had to delete several entire flocks (24+ birds) due to repeated MG symptoms to the point where I had to inject (M injection ) Pen Aquas, on a few birds, via muscular breast injection.
It revived them, but a week later they fell ill again.
I culled the flock & contacted the breeder.
She disapeared for a year, and is now selling again & I hope the birds are MG free.
And dang those Blue Copper Marans were gorgeous !!!
But full of MG.
I am sorry for your losses ! It hurts bad when you buy, hatch & raise babies, only to watch them fail & die.
MG has very apparent symptoms, and thanks for telling your story & helping new people her LEARN.
One of the most apparent symptoms of MG is "Pump Handle Respiration" which is the bird standing up staight (high) and gasping, then sinking down, only to resume his pump action, like the pump on a well. The second symptom just before the succomb, is turning blue, and the entire time you hear the gurgling of 'air-saculitis" where the air sacs of the bird (LUNGS) are so infected it is drowning...it would be our version of bad bad pnuemonia.
Thanks again for helping educate the new people here !
I hope you over come your issues, and let me know if I (or any of us oldies) can help !!)
YOU ARE AWESOME !!!
