I have 4 four month old chickies and one of my reds wont open one eye and I am thinking I took bad advice to put play sand and diatomaceous earth mixed together thinking that would keep them from getting mites but I am thinking the dust from it all is why she wont open one eye. It does open and there is no sign of infection yet and she seems ok otherwise. I need to know what i can use besides pine or straw because I am allergic to them. What is safe? I have some aspen snake bedding but I am afraid the pieces may be too small and dangerous if they eat them etc... They are not dusty at all though but I am not sure if that would be safe to use. Meanwhile I dug up regular old dirt and put it in there after clearing all the sand out. I am desperate for suggestions.
