I have heard that you shouldn't eat eggs from hens being treated with antibiotics. Mine were on Duramycin 10 from Durvet. It's a tetracycline Hydrochloride so I am assuming the rules holds for them also. I have continued to collect the eggs, but am keeping them separate. I am terrible frugal and can't bring myself to just pitch them. (It seems like it took FOREVER before they got around to laying.) So... could I feed the eggs back to the hens cooked in their oatmeal gruel? If they are already getting dosed I would think the eggs would have a minimal effect on them.
