I have a broody Cochin. As I realized that she was broody I put several eggs under her--she has been on them for 2 days. This morning she was off the nest and in another box--sitting on another egg. I felt the eggs and most were cool. I removed the ones that I hadn't marked and put in a different box. So, I am guessing that other chickens were wanting to lay on that nest and forced her out. She sat on another nest and never went back. I put her back on the original eggs. Are those eggs in that clutch still viable? Or have they cooled and now will not hatch?
