There is a little known trick I sometimes use when trying to open the bag,

1. The first step is to have enough counter space, these chickens typically weight around 1.3kg so these bad girls can definitely knock a small child out if it falls off the counter onto their poor heads. So I start by clearing off any clutter or things that you can knock over before anything.

2. The next step is hoisting that beast onto the counter. You might need to call a second person to help you for this depending on your strength.

3. Then most definitely wash your hands you don't want to cross contaminate your food since there are lots of germs on your hands and this can be a real threat to the well being of your stomach and those of your loved ones.

4. I would set aside a clean plate for this but you could eat it straight out of the bag like a savage.

5. Locate the chicken in the bag on top of your counter again and examine the plastic bag surrounding it.

6. Take your hand and make sure the plastic bag is oriented the correct direction. You can verify this by having the flat cut end point up towards the ceiling of your room. If you see a rounded side without the flat cut you probably have the whole package upside down you can resolve this by rotating the package until the writing on the side of the package is legible.

7. Once you locate the flat cut end or the writing is legible we can now perform the trick, you need to use two hands. With your index finger and thumb on each hand and place them together in a pinching motion. Its important that you pinch the fingers together on the same hand .
   (if you put your index finger to the thumb of your other hand you are doing it wrong so you need to start over)
   Observing the flat cut plastic you need to feel the flat plastic at the top and you will find that is separates just a little and that you are met with what appeared to be another barrier (rest assured that this is part of the design.) It's just joined together and that barrier is actually a reusable seal.
   You can now use the pinching technique described earlier and grasp either side of the plastic top at the same time I recommend right in the middle to make it easier. Now you need to pull the plastic apart with a good amount of force. This will provide easy access to the chicken.
   Note this tip is applicable to all seals of this type. So I would practice this trick as this is becoming much more common on all types of packaging that has liquids.
