We went to pick up wormer n stuff up today and spoke to the ccf co op area animal health lady, and she said that the powers that be weren't fully aware of the shortage, prior to be being alerted lately, she also said that some batches didn't pass, so a difficult time all round. She suggested at this time of year to use clikzen. Half the coverage of Clik, and she said due it being quite late that it was nt worth using Clik, but it's cheaper sister clikzen, also half the price, and an 8 day withdrawal, but still with the same active growth inhibitor x
