I am so upset because i can feel theres something wrong.
A hen that goes broody will lose color in her comb/wattles and they will appear dry and shriveled in comparison to the glossy, plump comb/wattles of a hen that is in production. It can take some time once a hen has gone out of a broody state for things to return to normal.
Of more concern is the behavior - you say she stopped setting on the eggs 2 days ago, can you think of anything that may have taken place to put her off the nest? Was the nest in a separate broody pen or was she brooding in the flock? When you say she "sits in the over saddly" - what are you meaning? I'm not really making it out and want to be sure I can answer your concerns as best as possible. Is she still seeming to be broody (setting in one place, fluffed up, defensive of her space) just no longer on her eggs? This can happen if the hen gets off the nest and returns to find another hen has hopped up to lay an egg, etc and the broody settles somewhere else, not realizing she is no longer on the eggs she was hatching.
She isn't sick - she is just broody. Unfortunately, the eggs have been unattended for too long at this point. When brooding in the flock this can happen. If/when I have a broody that has "lost" her nest I simply move her back to the appropriate nest of eggs. Because this can happen, I make a point of checking on the nests a few times a day during a brooding so that if she does get misplaced she is not gone too long before being placed back on the right spot. If you want to have her hatch eggs you might be better off putting her in a private brooding area (it can simply be a sectioned off area of the coop or a crate within the coop) and giving her a fresh clutch of fertile eggs. It is most likely she'll remain broody and see this clutch through to hatch if you do so in the next couple of days.
