I have an Easter Egger Chicken which is laying practice eggs almost daily. Yesterday I realized that she was closing her eyes a lot. Went over to check on her, I pet her for about 5sec and then she opened her eyes with a shock and ran away. She is not unbalanced but her poop was very bubbly at the top though it was normal on the bottom. She didn't lay an egg yesterday and she hasn't laid one today when all the others have. Also last night she did not sleep where she normally does.
