I have checked all the hens, NO LICE. He is defintely loaded with them. I have been putting Sevin in the nest boxes and apparently the bugs have found poor Shadow, who does not go in the nests, and have almost killed him. I found him yesterday weak and not able to stand. I have had him quaranteened in a crate with Sevin on the shavings, dusted him with it, gave electrolytes, yogurt. Is there anything else I can do for this poor boy? Thank you!
