I have found fleas on my birds. At first I thought they were mites but, no, they are tiny little fleas. I have dusted my peachick with a permethrin powder for poultry over the last several days and the fleas seem to be gone. I have also thoroughly dusted the pen and roost area. My question is: how often do I apply the powder to the pen and how often do I treat the peafowl? I want to eradicate the fleas but I don't want to overdo it with my peafowl, especially the chicks. The directions on the container don't indicate how often to use it safely and effectively. Any advice?
