I have had chickens for 8 years and this is something new. 2 or 3 of my hen's (I have 7) eggs have a strange chemical smell. This started a day or two ago. I am worried that a chemical is washing into the creek water that the hens have access to. The smell is faint yet sickening. It smells a bit like goat milk but more like a strange chemical. We are afraid to eat the strange smelling eggs and wondered if we should eat any eggs from our chickens right now. They sometimes eat from our compost pile but have been doing this for years with no problem.
