My DH thinks that, too. He used to roll his eyes but now after 4 yrs of helping me with chickens, he just sighs and does whatever I ask. I would rather err on the side of over caution than it regret it later. Even with my OCD chicken keeping, accidents sometimes happen. Last year, I made the mistake of putting a half filled bucket of water in a grow out pen at the farm. The chicks in the pen were almost full sized but I guess that they were so thirsty that the mobbed the bucket. Two went head down in it and drowned.
