Im also hatching my first time. My hen is sitting on 23 eggs and is on day 13. I just went to check on her and 2 eggs were missing whilst one was deep under the hay and was cold. The hay had some blood and yolk on it. I wiped all the eggs with a dry clean sock. I didnt try to rub off the dried yolk which had stuck to some off the eggs shells. Is it ok if i leave them like that?
Could it be my hen who ate the eggs or mice?
I noticed no left over shells so who ever ate it, ate all of it!
I also candled the eggs and all had developed. About 18 were ceftainly moving and rest 3 i was unsure of but still left them in.
Welcome to BYC! I don't have any advice because I have my first broody sitting on eggs as well. Coincidentally, she is also on day 13, so we'll have to compare notes.
