Pink flowers, red berries

Along the chain link fence that I want to pull out are these bushes.  Some are over 10 feet tall, in the spring time they are covered in pink flowers which turn into these red berries.  They are a kinda pretty wall however they do not keep the chickens out and the chickens need to stay out of my yard.  I'm planning on pulling them all out while the fence gets done but may want to plant them again after the fence is done, we'll see.  The little birds like chickadees and finches like to hang out in them.  This summer with new puppies I pulled down the bird feeder too so the yard has been pretty quiet.
