put locks on all the doors to your coops/bird type areas, your family clearly doesn't understand chickens, mine have no idea what i do for all the birds them, but at least they don't touch any of my birds unless they know what their doing or i give them instructions. As for last chance, you can hatch birds in a small apartment or dorm room, right? My 21 year old sister almost od'd my birds on a quarter bottle of ivectermicin cause it kinda looked like vitamins, luckily she checked the label before giving the birds the water.
