Thanks for all the kind words. If it is a vitamin deficiency, it will take up to 2 weeks to show improvement. So, I would guess 3 weeks would be a good time frame. However, you will notice that some will go downhill rapidly and you can make the judgement call at that time. I have a pullet, my son's favorite, that up until a few days ago was living a very happy life even without being able to forage. I home school and she is with us from sun up to sundown. I was using any method that I read to help her and was praying hard that I would find the 'cure'. Unfortunately, Marek's doesn't want us to find a cure....she is now at the stage, after 7 months, that I am thinking she will need to be put down. Marek's is a cancer and like cancer, goes into remission. Some stay in remission, most, do not. I will give her a couple more days and if improvement isn't seen she will go to heaven to rejoin all her buddies, and her man, that have gone before her. Thinking about them makes me weep...
As for them just being chickens...here, they are pets. First and foremost. My kids love them as do I. Even my seemingly unaffected DH cried like a baby when his favorite, Phyllis, died. She was a beautiful SQ white crested, black polish. I treat them as I would any other pet. They are given a chance to get better and then, die with dignity if the need arises.
Addictingchickens....that is a whole lot of chickens to lose in a year and a half. Have you ever had a necropsy done on any? If not, I would surely think about having one done so that you know what you are dealing with.
tahlias....I will give you my opinion and this comes straight from the heart and from experience. Hold off on getting babies until you know for sure what you are dealing with. If it is Marek's, the babies must be vaccinated before they are exposed. Meaning, at day 1 before they come to your house. After that, you need to give them at least 2 weeks of absolute quarantine and in all honesty, 10 - 12 weeks is better. That means, you have to shower in the morning, take care of the babies..keeping jacket, shoes, etc...just for them. Then, take care of the other chickens. If you have to go back to the babies, it's the same thing. I literally spray myself from top to bottom with oxine before I check on them at night. Plus, it means finding a spot in the yard where no other birds have been to allow them to get out and be chickens. Even with all this, some can be infected. I have lost a silver grey dorking that I was thrilled to have found...she was 11 weeks old
Again, the best advice that I can give is...if any die, have a necropsy done. To date, I've have 2 done....both showing Marek's. Two different birds, two different breeds, different symptoms, same disease...and, neither showed the symptoms listed under what to look for in Marek's.
