This is my story this is my song lol . After the first inland nat my birds started to go wrong maybe before that ! I had a bird come home late from fed race the next day , almost straight away he started drinking lots water then noticed his nest box covered in water so out the loft he went into a basket and treated for coxy after 5days no change basket was soaked so cankered him then gave parastop for a week , while he was locked in basket another 2 went down with same so put them in spare loft and gave coxy treatment again it did not do anything so sent test away to belgica who told me to treat for coxy but also jag again for para which had been done in March and also jag everything so I did against my own belief that it was not para , in mean time 1st bird completely recovered ,was given 4/1 from belgica but made no diff so in end I destroyed 12 yearlings that got it and that was the funny thing not a older bird got it ? . A week after jagging my ybs they started to get wet droppings and not looking great ,they had been flying great at home , so sent test away told again to jag birds for para (they had only been done a few weeks earlier) also treated for coxy no good then put them on 4/1no diff contacted belgica and done test with other vet and told to jag again ? Now my patience was thin here and told them that why am I jagging them 3 times if vaccine is ment to work first time ? They are now getting tested again in a more complex manner . I don't want the kill them brigade as that is easy way and answers nowt but have disposed of any that have struggled . The reason for this long winded yarn is WHY do we vaccinate if it does not protect them at all ! Also I am not alone with this problem which I know for sure and they think kill a few and all is ok carry on regardless and we wonder why we are losing birds so easy .
