It's all about family

I have watched a Finnish horror movie called Hatching. Noticed how attractive the people are in this town. There is a pretty gross scene which I won't go into. This ideal family living in the suburbs. There was a bird that had made it's way into the house. Later on the daughter Tinja finds an egg. She decides to keep it in her room. It hatches and there is a bird like human clone. She gives it the name Alli. They have a psychic connection. Sophia Heikkila, Siiri Solalinna. The young actress is good at gymnastics like her character. The mother is attractive. Overbearing, having an affair, vlogging. The dad does his own thing. The young brother seems to have a hatred for his sister. There has be some kind of metaphor regarding this story. You might also like The New Daughter.
