Tried removing some seeds from a dry morning glory vine so they dont plant, only got about 1/4th of them after half a hour

I gotta try and remove the full vine to chicken safe my yard
Planning to completely rip up the stuff from last year in the garden too that made it through the winter as the kale is starting to rot, tomato vines are fully dried, and the carrots are just short and piled on each other.
Also going to fence my favorite blueberry bush since I dont want the girls getting those since they only produce a few a year and they are my all time favorite (they will get tons of fresh mulberries from our tree though instead

)
