So, someone "donated" an old rooster to us. We are a non-profit rescue farm so we get all sorts of critters. I'm assuming the people that had the rooster either had no clue how to even look for lice, or they knew of the roosters condition and that's why he's here. Either way, he's with us now. This poor guy is about 11 years old and only has one eye. He's a VERY nice guy. I gave him a bath yesterday with Happy Jack flea & tick shampoo. This is what's in it. ACTIVE INGREDIENTS: Pyrethrins 0.150% *Piperonyl Butoxide, Technical 0.300% **N-Octyl Bicycloheptene Dicarboximide 0.500% OTHER INGREDIENTS: 99.050% TOTAL 100.00% All the lice seem to be gone, or at least dead, that I can see. Question is, does this shampoo also kill the eggs that are on his feathers? I cut off the biggest balls of eggs, which means I cut off some feathers. I have no idea if this is a smart thing to do to a chicken? Didn't dare pluck any feathers. Is there anything else I should do for this rooster? He's in a room by himself so he won't give any lice to any chickens on the farm...or any other bugs that I might not be able to see.
