You can remove the silver ring that holds the rubber stopper in place. Its very thin and easy to tear. The rubber stopper can be lifted out and a syringe, minus needle, inserted into the liquid. Push the plunger all the way to the bottom of the syringe, then slowly pull the plunger backwards..the liquid will fill the syringe. Push the plunger back down to remove excess liquid until the level of liquid reaches the cc (or ml) amt you want. I understand dosage should be 1/4 cc for an adult hen. You can try to drip it into the mouth, but I think it taste pretty nasty...if you have a needle it really is easier to inject into the breast muscle. If you cant do it, do you have a friend that takes insulin injections or is a nurse?
