I have a 9 month old black Australorp who for the past 3 weeks has shown signs of Mareks. Initially I thought it may have been worms, coccidiosis or dehydration as it's been quite hot on & off in Victoria, so have treated for everything until now she appears somewhat paralysed.
Spoke with her breeder and found there was NO vaccination done as he believes he can breed Marek resistant birds.
Great........... now I am concerned my other 3 hens of the same age (same breeder) and 2yr old Rooster will come down with the virus. I've been hand feeding as the sick hen who can't stand anymore, she eats and drinks well if I hand it to her but this can only go on for so long.
Does anyone know if an older bird coming down with this virus can fight it and perhaps survive with a disability or should I consider culling now even though she is still bright and eats well?
Obviously culling has been my last resort but I am concerned about how long this will go on for an the risk to my other birds.
Thanking you all in advance for some support
