I have three barred rocks, who have always been quiet, very sweet and have always look for ways to escape the coop. But for the past few days, when I go to feed them in the morning, they just sit on the ground, with their eyes half-closed and don’t eat. We ran out of chicken food a few days before, so they were served bread and rice for a while until the new bag was delivered. I thought their behavior may be due to the food switch, but they’ve always eaten whatever I give them, and they haven’t eaten in about four days now (they will occasionally peck at some food, but only a few pellets a day. They drink water though) They haven’t eaten anything that’s bad for them recently. I checked them for worms. I checked the area for any predators that might have scared them. And now they aren’t laying. They’re always so curious, scratching around in the run 24/7, but now they have no personality whatsoever. They don’t want to explore the yard, which they always adored. Does anyone know what’s wrong with them? Thank you.
