Hello my friend @brian.rrr I hope you're fine. Well personally I would say that it was good to remove the bird's nest and cover it with that ball because if you kept leaving them there then they would lay eggs in the nest and then they would keep growing more and more birds there and once they grew up several birds there if it was to make it more difficult to remove the nest, because there are newborn birds more that are growing, it was harder for you to remove them because they had the home completely made. In your case you took it off in time because they had not yet laid eggs so it was good that you removed it from the rafters of your backyard, so you take away the headache of having to clean the poop always. And the idea of passing the nest to a tree is perfect, because it is much better because they can also do all their needs whether they mess up or not, and there they can have their children quiet in the spring.
