Ok, all this ILT talk has gotten me pretty scared...even though I generally don't "wheel and deal" in chickens. I've got a couple of questions about ILT, and I can't seem to find any clear cut answers. If a bird is exposed to other birds with ILT, but never shows any symptoms itself, and is vaccinated for the disease...is it still an ILT carrier? And can this bird be tested? If a bird such as this is possible, then how many backyard flocks may actually have ILT carriers in them going undetected? SCARY!
