Hi everyone. I was out in the loft a little while ago with my husband and we noticed a fly on one of our young birds. We watched it burrow in to the feathers on the bird's back so Mike caught the bird and we inspected it and sure enough the fly came out and flew aroung but we got it. We watched the other birds for awhile and they seemed to be scratching quite a bit. We were discussing giving them Ivomec sheep drench in their bathwater (3cc's per gal). Is there a better way to treat your birds or is this the recommended application?Thankyou.
