On your advice, I have finally managed to sex my geese - well, I think I have! One goose has started laying so I know she's female. 1 has started bonking her so I'm presuming he's male! The female that's laying has developed something that looks like an egg sack between her legs. One of my other geese has developed the same 'egg sack' but I can't find any eggs - could this be a phantom preg... I mean layer? The 4th goose I'm also presumimg is male as no: 1 male goose keeps fighting him! Admittedly, my 4 geese are free range during the day so it's possible she's very clever at hiding her eggs. But ....... is it possible that a female can develop this egg sack before laying or not start laying this late?
