Thanks for looking. The largest one is definitely a female, she is feathering now in medium and dark grey tones all over. The smallest one is probably male, light bill. Its the middle one that is my "Victor/Victoria" gosling, I'm just not sure. It will all come out in the wash, I'll know in a few weeks tops.
I guess its not as bad as my turkeys, I really didn't know for sure for about 4 1/2 - 5 months.
