I just walked in the "COOP" & one of my LARGE breed cornish was walking away & BLOOP an egg just fell out of her! I picked it up & it looked OK except that is was quite a bit smaller than usuall . WHAT I WAS disturbed about is it looked as though there was some yolk was on the outside of the shell. (yellow) I went outside & cracked it. the egg although small looked OK. any ideas on the yellow? EDIT the shell was NOT BROKEN when I picked it up.
