Last week our family ate some hamburger that turned out to be bad and we all got food poisoning. Before I knew this I gave my toddler's leftovers to our chickens. They had been laying about 4 eggs a day but now they're only laying 1 or 2. They are also not eating as much as usual. Are their eggs safe to eat? Or do we need to discard them until they start laying and eating at their usual rate again?
