I have a four year old Buff Orpington who I suspect has external parasites although I've checked her frequently and see nothing. She started acting and looking like she didn't feel well last week and while I had her inside checking for parasites, noticed she had started wheezing. She also had diarrhea so had a fecal done. She had no internal parasites or cocci. Five days of Baytril cleared the wheezing and diarrhea. This whole time she was/is constantly scratching, pecking at herself, shaking her head and spends her days in the dust bath (dirt, sand and wood ash). I still see no parasites but think I need to treat her for them, don't know what else to do. She seems to be very uncomfortable. I have also checked for ear mites and saw none. I have one other chicken left, she shows no sign of parasites either and no scratching or pecking at herself. I have a bottle of Poultry Protector and wonder if it is effective, it says it is but the ingredients do not include permethrin. I would like to treat her this evening but will wait until I can get to town tomorrow if I need another product, assuming I can even find it here. I hope someone can give me suggestions for what I can do for her. Thanks.
