HAHA when I first heard about this I started picturing fake chicken body parts like with semen collection for horses!How is that even done? The rooster part I mean!
could be tics. they hook up to the skin like an IV full of poison. did they free range in grass too tall? taller than them? and did you stop them from taking dust baths? if it is tics, fence off, or cut grass that is taller than 4 inches. if you have grass in your run were taco and elena died. put you chickens in their coop, and poor lots of boiling water in the grass. be carefull, you dont want to get the tics on you...expose little of your skin (especially lower half of your body). it would be impossible to check all chickens. the other possibility is a tape worm or some other kind of worm. they could have got worms by either drinking dirty puddles of water, or drink pond water. stop your chickens from eating things like LOL Uncooked meat, or raw vegis. also dont let them free range when the grass is too wet.
