I had put two eggs under my hen and 1 hatched on time but one didn't and it's on day 27 as of today . I broke open the egg on the 25th day to see if anything was growing and it was moving in its sack . I didn't tear the sack in side the egg so I put medical tape over the small hole and put it back under the hen . need help on what to do . should I leave it under her or open it my self . Im new to hatching eggs and any help would be appreciated very much .
