First time posting here... I have a specked sussex who I am pretty sure has Marek's. She has the paralized legs- one in front and one in back. All the other symptoms too. I've isolated her and have cleaned out the coop. No vaccinations on any of the flock- bought from breeder (have americaunas, leghorns, & a dom point). I'm a first time chicken owner, so it took me until yesterday to realize what she had. Was going to wait until today to put her town.... I have been keeping her inside by the wood stove and have been giving her Colloidal Silver (natural antibiotic). She had gotten so bad- stopped eating, nearly lost control of her neck, very thin, loosing feathers, barely awake. But- this morning- she miraculously has her appetite back and is perking her neck up. She still has no function of her legs. Do you think it is possible that she is surviving the Marek's? Should I give her some more time or am I risking the spread of the disease to the rest of my 10 birds? I will put her down if necessary- just wanted to check here first... Thanks for any help!
