I got some silkie chicks from a local breeder a week ago. Currently I have them in my tub. It's lined and has a lite layer of shavings. I noticed today a tiny yellowish bug on my hand after cleaning their water and refilling their feed. After closer inspection it looks like there are more on the chicks. I haven't see too many yet but they are definitely there. I think they may be mites but I'm not 100% sure. I will completely strip their tub brooder and clean it. Are there any treatments I can do to get rid of the ones on the chicks. They are only 1 - 3 weeks old. I don't want to use any kind of chemical base treatment. Any suggestions?
