Hope this finds you well. I am staying at a cousins apartment. There is a pigeon on the window sill with eggs. Am I able to do shiluach haken with this pigeon? It’s not my house and the window belongs to my cousins. I can’t ask them to be mafkir the bird- they irreligious
How do I know if it’s the female bird?
You can do the mitzva with these birds, because they are still considered hefker. The two parent birds take turns sitting on the eggs, and the mother bird sits on the eggs at night. Therefore at night is when you can do the mitzva.
