right i think i have a problem and wonder if any one could help, i have indian runner ducks and one of the girls lays an egg everyday, today she layed it and i collected it at around 4pm witch was later than normal as they are normally there at about 7am, when i collected the egg there was alot of jelly around the area which i presume is the white of the egg then i watched her from a while and a yolk came out on its own, i have had them lay eggs before that just had no shell but still had the membrane? but this time there wasnt even a membrane. is it something to worry about or had she just layed an egg that wasnt developed?
