Hi there - I have 3 day old chicks and they are scratching around the brooder and pecking at the bottom. They definitely know where their food and water is so I don't have any paper towel down. I found they were getting stuck under the paper towels. I noticed their crops are really full. But they've been eating a lot today. Should I be concerned? I had bought some "chick" grit but its not very fine and is recommended for 2 weeks plus. Any recommendations?
