Hmm, that's strange. Are you talking chicks or adults? I raise most of my chicks in my bedroom in a brooder. When they get feathered enough to go without the heat lamp, I prefer to take the water and possibly food out overnight, but not for that reason...
For adults, only take out the waterer at night as it gets cold and its not good if they drink it.Take the feeder out overnight to keep rats away, by all means. They will not overeat.
Broilers will eat noticeably more than other breeds.
The birds will retire for bed with a nice full crop, and then digest that overnight. They cannot see well in the dark, so they will not be eating at night.
Clearly stated.As others said, they don’t eat or drink at night. Even when nights are long and days are short, I never leave water in my laying flock’s coop because it gets knocked around. I leave food in there just because it’s easier. Even my broilers go to bed without food and water after the age of three weeks. I never remove food and water from chicks.
I used to keep a light on for my chickens because I worried that they couldn’t see at night But I realized that they would stay up pecking each other. now I turn off the light as soon as they are all comfortable.We have lights in the coop of adults. We turn it on for 4-5 more hours after sunset.
