Sometimes I just don't know what to think! My current hen that had total leg paralysis yesterday is now standing . If it's Marek's there is nothing I can do to change what will happen. But I'm still going to treat for dehydration and malnutrition, possible Vitamin B deficiency, possible chronic intestinal problems needing antibiotics and anti-cocci.
Texas A&M does pcr testing on a blood samples. PCR is when they take a small amount of dna and scientifically increase the amount present. Blood from a live chicken. However, testing blood for Marek's may or may not be accurate because it can only tell you if the chicken has been exposed to Marek's . To get an accurate test, you have to have tumors that look like Marek's tumors, a histology exam to see if there are microscopic tumors, and pcr testing. If all are positive, it tells the pathologist that the chicken has Marek's tumors and has died most likely from the tumors.
I still don't think that a nine year old roo died from Marek's tumors, I think it's more likely that his tumors are related to something else. There are many different types of tumors, think of all the different cancers in humans.
Silkie hens are not known to be great layers. When they are broody they may not lay for months!. Especially when it's hot. And on warm nights are they gaping or just warm and panting? What does the poo look like? Have they laid any eggs?
If you brought these 3 silkies into contact with supposed Marek's at your home, and they are now 16 weeks old and not suffering from paralysis, I would not be looking for trouble, LOL. And I don't believe in hypericum.
I wasn't having good laying in my flock and I switched them from 16% protein to 18% protein and they have been laying nicely for months now. But my 10 silkies born in March are still too young to lay I think.
I see. So I would have to have a histology exam, not sure they even kept the tumors and I'm not digging my roo up! I guess I never mentioned, but my hens are about 1.5 -2+ years old. I didn't buy them as chicks. One never laid and I'm not sure the breeder believed me, or thought I could be sure, but I was pretty sure. One went broody, but is back now and had stopped laying a couple of weeks before. And one stopped for no reason. They've not laid one egg for about six weeks.
Their poo - pretty dark, even blackish, but I feed them some blueberries everyday, not a lot, and I've thought this is the reason. I don't know if this is significant. Some look great form-wise, some have watery urates with broken up solids, some brownish diareha, although only now and then. Fecals on my roo and on a combined hen both were negative - for everything including giardia.
They were gaping for sure, but were not tonight. When they were, however, they were doing it for minutes at a time, not just a few times. They may do it every now and then otherwise.
They are on 18% protein with oyster shell free choice, but I was getting them some layer tomorrow (today).
And I have never believed much in homeopathic medicine, but there was a change in eating three days in. This may be coincidence for sure, but it is what happened. Like I said, they are not acting as if they are sick. I think your silkies are too young to lay, yes.
