So, I got a new batch of baby chicks. I put them in the basement as always with the heat lamp inside a huge cage used for my former guinea pig. I turn the overhead light on every morning to simulate daylight and shut it off at sundown. I check them 4 times a day and handle them. I have raised 25 chicks this way over the years. Well, I go down in the morning; turn overhead light on; and change water and handle. Everyone is great. I have a playdate in the afternoon and bring the other mother and child downstairs to see the chicks and they are GONE. They just vanished. There is no way they could have gotten out on their own. The cage has a solid bottom with solid sides about 6 inches that changes to a wire top. The wire has wire pieces that are fairly close together- maybe an inch. The 2 closures on the top of cage were secure. The bottom of cage was secure to the top of cage. I looked everywhere and didn't see or hear anything. It is really freaking us all out. It's like they just vanished out of thin air. What on earth could have possibly happened?
