I talked to the vet at UT today. She said she if the birds were vaccinated as chicks, the breeder says they were, that is unlikely for both of them to have mereks. She said vaccines are not 100%, but two failing are unlikely. I'm taking them in tomorrow for an examination, the roo passed away today, the pullet is still alive. They're going to do a necropsy on him and they will probably euthanize her and do some testing. I'll post tomorrow after our visit. Thanks so much for the help and support. So far no signs or symptoms from the other 3 I ordered. She says no one in her flock is sick and my friend that ordered some says his aren't sick either.
I misunderstood! I thought you wanted to vaccinate your flock now that there was a Marek's scare.
There are a few explinations:
1. It's not Marek's,
2. It is Marek's and the chicks were improperly vaccinated OR did not build resistance (approximately 10% of chicks won't), or,
3. It is a mutated form of Marek's (they exist) which is particularly virulent and the chicks most susceptible to it succumbed.
It is very important to note-- according to what I was told by the vet / UoGA, vaccinated birds are harder to test for Marek's and might give a false negative depending on what kind of test is run. It might be worth asking to see if their poultry expert(s) agree with what I was told.
For those of you who have given the super B to your mareks birds do they ever get better? Or is it just extending their misery?Is the DE working, can you tell? You will get all sorts of responses as to the effectiveness of DE on an active infestation. It is my personal thought that it is best as a preventative. I say this as a person that is loathe to use toxins and pesticides, but-- once there is an infestation on a bird, it is probably worthwhile to use poultry dust or your lice killer of choice, as they can weaken a bird very rapidly.One more: my lavender with wrys neck has lice I think(small yellowish bugs) I've been dusting her with DE is there anything else I should try? None of my other birds have the lice like her I think it's because she is unable to preen her self
Thanks
Here are two photos of poultry lice.
