I agree with Ivan, eloquent. indeed. Here is a good article on the vaccinations for ILT, if anyone is interested: http://www.thepoultrysite.com/articles/1430/new-treatments-offer-help-against-surging-ilt-in-poultry The problem with vaccinations is that you must be VERY careful as certain types actually make the bird a carrier of the disease you are vaccinating against. There are so many diseases of poultry that it could be cost- prohibitive to vaccinate against every single disease a chicken may get in its life, plus they must be vaccinated for certain things at different times, some have boosters to be given later, etc, etc. It's quite a trap to start trying to vaccinate for every single disease. I do not vaccinate for anything and I refuse to start. The best cure for disease is euthanasia. It's also the most cost-effective for a backyard flock. Simple and to the point. Jules, again, I am so very sorry. My heart breaks for you. You are very brave and made such a hard, but I believe, wise, decision. Anyone coming here must spray their shoes with an Oxine solution. No one who comes to get birds or eggs goes into my coops or pens and I'm tightening security in the future as well.
