My friends father had some birds nest in his tree. So somebody said, “hey, you can do shiluach hakan!”
I think this is a mistake. “Asher korcha baderech” – the nest can’t be on private property.
I got my house this way. I was at a friend’s house and he told me he was going to do shiluach hakan on the birds in his backyard tree. I told him it can’t be private property, so he was immediately mafkir the tract. While he was up in the tree, I got two eidim and gained a piece of land.
