My 6-week Silkie is totally onto me trying to "sneak" vitamins into her food, applesauce, yogurt, etc. you name it I've tried it and she'll have nothing to do with it. I recently tried holding her cradled in my arm on her back, but she holds her beak SHUT TIGHT. What do I do? I tried looking to see if I could somehow pry her beak open, and that does not appear to be an option. Open says me and pretty please didn't work either. Suggestions?
