As title says, my male canary somehow managed to fly out. I open the middle of both cages to each other, and they fly into each one. Someone in the house wiped the table and pushed the cages away. And left just enough distance apart for him to fly out. He flew out, I had to try getting him back into his cage trying to lure him back. He went to the basement and there was a bit of salt on the ground, which he began chewing and eating. I managed to get him in a cardboard box and now he's back in the cage. However, he is puffy and his eyes are squinting, closing shut sometimes. I'm not sure if this is due to the salt or just him getting scared from the whole experience. Anything I need to do immediately to treat him?
