I'm taking care of pigeon who lost the ability to fly cuz one of her wings are broken but her injury already recovered, tbh i don't know alot about pigeon I'm just giving her water and food and she's staying on large cage, after taking care of her for about 9 months i have never heard her voice i though she lost the ability to talk but these days I'm hearing her screaming at night and i don't know why? Is it because she feels lonely? I didn't let her walk on my outside house cuz i though she will feels sad seeing all flying birds while she can't, but after hearing her screams i don't know what's the best for her can u advice me?
