Oh that's awful Fluffy, I would be sick if someone stole one of my birds.How cute! Sort of the opposite happened to me. Had a very wild hen given to me by an acquaintance for brooding. Long story short, she broke two weeks later, and a week after that escaped my pen and my property
she got effing stolen the very next day, before I could catch her![]()
You have no idea how they are being treated, or if they are even alive! 
I kept mine in flight aviaries and they became powerful fliers! I never lost any of them, fortunately they were smart enough to follow the sounds of all the crowing home. Most never went far once they realized they were on the outside of the aviary. One of my males flew straight out the door and did a huge lap of the valley, I was sure he was gone as I helplessly watched him fly out of sight. 30 mins later I heard him calling up the hill, he kept calling, I called his name, he walked toward me, I to him. Eventually I was able to grab him and get him home. I gave him a good scolding on the walk back though!
