I have already used Wazine and am now ready to deworm my hens using Ivermectin. I have read in previous posts to get the 5% blue pour-on but my local TSC doesn't have that (I don't think). Here is what they have: Iver-On Ivermectin Pour -On for Cattle Countains: 5mg ivermectin/mL Is this the same as the 5%?? Can I use this and if so, do I still follow standard procedures of .5cc for large hens? Thanks for any help!
