I recently asked my egg buyers to start saving their egg shells so the flock can eat them. They agreed bc they love the tastet eggs it’s just I haven’t had a problem until now. I opened one of the bags of shells and it smelt so bad!!! The others havent. They left a whole bunch of yolk still in the shells. I baked them and crushed them up but they still stink. CAn the chickens have them still?
