Well done Walter, good honest post, just what the fancy needs, not a cover up. I use Nobilis myself and I've probably said before my wife does the vaccination and I hold the bird, takes so long to do 60 I get bored but go with it as she is an ex-nurse and has to have it right, I check the next day to see if any have an oily patch on the spot (If any have they need to be done again, the dosage is very small and any leakage would render it not safe) and I always have at least one, that's being mega careful, That's why I like Nobilis being oil based you can check the following day, It's very important to get this one right. I don't race from home, only one -lofts but have never had young bird sickness or PMV.
