Attention greetings.
As you can see in the image below, the chickens come from the portal and spin around the spaceship (sorry if the image is not clear to you) but not all attack at the same time. It is time to start becoming a portal. The number of chickens that portals in one turn is 7. If you do not kill them, they will go to the other side. There are anomalies in the four corners (between the portals).
Thanks for reading
