I tell them to feed/water them and if I took pictures and showed them to my parents they would tell me to stop tattletailing.Dare I ask the you have a "smartphone"?
Used the camera. Have a calendar on the fridge with each siblings name on corresponding day for chickens feed/water duty.
On the days they have duty you take a pic (once or twice a day?) And share with parents when you have to feed/water them because the Sibley is neglecting them and you don't want them to starve or worse, die.
Key thing here is document. No Whining! Just the facts. AND if a sibling actually starts to do it right and thoughtfully the pictures documenting them become positive reinforcement when you can then show parents who is finally stepping up to their responsibility....
