Someone put a random rooster in one of my cages yesterday

Several cages outside, if they're cheap I will get them because I get a lot of animals and if someone needs one I will give them a cage, the one that this Rooster's in is my rat's cage after my last one passed away I took it outside to disassemble it and just haven't yet, woke up this morning and someone shoved him in it don't know who don't know why but I guess I have a free rooster to add to my rooster flock
