My chicks (supposed to be 2 weeks old but think one of them is 3) seem to be full of extra energy today they are happily chirping away and makeing a mess of there food and water...scratching around and flinging pine...so I picked them up a mirror with a bell on the bottom to give them somethig else to do and they love it...although when the first bird hit the bell all 4 of them froze for about 30 seconds! Am I reading the signs right and they are just high energy today?
