No, there were no nests there, and no birds either; we looked for a long time... I don't know where it came from...
And we're feeding it with natural food; my brother already went to the pet store and bought bloodworms (red worms), and that's what we're feeding it now))) We give them to it with tweezers; at first, it wouldn't open its beak, but after several attempts, it finally did and ate the worm, and now it opens its mouth on its own when it's hungry))) And it drinks water from a finger; it can't drink from a dish on its own.
P.S. Don't forget to wash your hands before feeding the chicks like that...
