Unpack your chicken breasts. Pat dry with a paper towel and place them into the slow cooker.
Pour the chicken broth.
Sprinkle the seasoning, celery seeds, garlic salt, and lemon pepper.
Cover and cook on low for 6 hours or on high for 4 hours.
Once cooked, it is time to shred. This step can be done in different ways. I like to carefully take the chicken breast out of the slow cooker into a deep bowl and shred using 2 forks. You can also shred in the slow cooker but be careful as there is hot liquid. Also, another technique is to take the chicken breasts out and place in a bowl and for shredding you can use a hand mixer.
Once the chicken has been shredded, place back into the slow cooker and mix well with the remaining liquid. Set aside until ready to serve.
