I'm not sure if I am posting this question in the correct area, or if I even worded my title correctly. My question is NOT a how long to withhold from eating eggs after worming with Valbazen, I know the answer is 14 days. My question is can I toss the innards of the egg in the trash and keep the egg shells for composting? Is it safe? Would really much of the Valbazen get into the ground from the egg shells and if so how bad would it be? I only have 5 hens right now so we are not talking about many eggs, maybe 4 dozen total? I just hate the thought of completely waisting the eggs and was hoping I could at least save the shells to put into the compost pile. TIA!
