My chicks are now 10 weeks old. One has all her fethers on her now the other 2 are a little behind but are gettin there, not sure why. Anyways. Since the weather has been nice i let them go outside in the babygate to run around and play. Yesterday i went to change their water and noticed these VERY TINY brown bugs all over te top of the cage and inside of it as well and all over the chicks. From what i have read i think tese are mites. I have read some things about the DE stuff and i think that will help but i am not sure of the exact name that i need to look for while looking for it. I do know that yo are suppose to use the food grade one not pool. I also heard someone saying seven dust will work. Is this true? and if so can anyone help me as to how to go about getting rid of them. Im not sure if they harm the chicks of not.
