How big compared to these blobs:From the tip of the index finger past the first joint. Some of it got smeared on his beak/side of his face. I don't think any got in his eye.
Oh, and I don't think the dogs have heartworms, their last checks were fine, but that was before we moved to our new place, got chickens and met the helpful neighbor who thinks a flea bath is all she needs for her dog. Mine are now flea infested and get treated more often with flea preventative. The chickens don't seem to have fleas, can they even get fleas?
