Does anyone know about the safety of using plastic feeders and waterers? I've been hearing alot of negative stuff about plastics / plasticides and I am wondering if anyone has more info on this. I am presently using a plastic chick feeder but switcfhed my waterer bottle to a mason jar instead of plastic...... I am wondering about any risk to our birds and thier eggs / offspring.... Does anyone have any recommendations on feeder / waters? I need to get the big ones now that the girls are in ther coop. Thanks!
