I have 5, 2 week old poults. They are currently living in a 60 gallon fish tank. I had to remove the lid of the fish tank for the heat lamp and one brave little poult has made a grand escape twice, so I covered the top of the tank in sheets of tin foil to prevent escape. Every morning when I come out the tin foil in on the floor in the fish tank and this morning it had been torn into little pieces. The tinfoil was pretty secure so I am confused are they pulling it down to play w/ it? The first day I thought it may have just fallen. But now that its happening more frequently I am starting to wonder. Any thoughts?
