this time i went with animalgenetics.com in ohio. i paid 24.50 for ONE test. i was only doing one and it was a US site so i went for it. i have only don't it the one other time for two silkies and it was $25 ea. BUT there was a site in ontario canada where it was $15 ea for blood sample or 5 for $50. if i did not have the shell from this particular bird i would have sent to canada and done the blood test but much later. as a tiny chic is way to small to cut its nail...i was very squeamish to do that last time but they were older. i don't really remember how old but they had nails. these tiny ones barely show nails at this point. even tho they said (Ohio firm) they tested shells it did not say how to ship etc so i called. you can print out all the forms online. one site said just mail the shells in a paper envelope, ok if it breaks up but this company said no, mail wrapped in something protective so it does not break up...anyway they walk you thru it no big deal. the other two tests were correct. it was blood sample and its DNA...it would be very odd if it was wrong...i don't see how it could be. ??? but never say never i guess....cross contamination or something?
