You feed them and water them.
If the others don't, ignore their laziness and keep feeding and watering.
Worse case scenario is they are fed too much (not possible with chicks) or watered too much (it's a good thing)
I literally shop sales. Once a month I buy staples.
Today, I had 50 pounds of pork loin in my cart (1.55/lb) that they took issue with. Why? I have no clue.... they appeared to be happy with cup-a-noodles and Mac n cheese.
Keep an eye on your cart vs sticking your nose in mine.
Wait.... I said that today. People don't comprehend shopping once a month. Therefor make comments about me hoarding like some doomsday freak.
I dislike people.
