We have two cute bantam couchins (one red) and they are roughly 2 and 3 weeks old (about 60 and 100 grams). Today they suddenly started complaining A LOT, and nothing we did, changing water, litter, food, lighting, heat, shower, hair dryer, did anything to calm them down. They usually get excited and jump out of their cage when they see us, and it seems normally affectionate of a chick. But today they will not stop complaining as loudly as ever and trying to jump out of their cages, and they are eating strangely. They peck at their food only a few seconds before running amuck. Checked for sticky poo, nothing seems to be wrong. Feed is standard chick starter feed from southerns states (no medications added). We do not give them "grit." are they just being clingy or is this hinting at a real problem? Could they be too hot?
