Next question. I checked all air sacs today and all but one look exactly the way they are supposed to on day 13. The one that is not looking as it should appears to have lost more liquid than all the others. The chick is still very active inside so I am assuming that all is well. The air sac looks more like it should on day 18. Also, this is not one of the ones with the detached air sacs, those two look great. Is there something I should be doing for this egg?
