Clikzin spreads through the whole body but crovect only protects what fleece it touches though. I’ve had lambs struck at the beginning of the 6th week of crovect but have been fully protected for the full 8 weeks of clikzinI didn't make that very clear, confused myself rereading it. I ment to say I wouldn't bother looking at clikzin at £120 as @Al R posted (I understand he has to) when crovect is somewhere around half price.
