I do not have geese. I never planned on having any geese........ BUT......... a friend of mine has some Sebastopols and said I can have some when the eggs hatch. Well, how can I say no??? I can't. They are stunning. I was reading that you can tell the sex when they are day olds by color. Darker ones are female lighter ones are male. As they get older how do you tell who is who? With ducks, a drake has a curled feather and females don't. Is there anything similiar to telling the difference with Sebastopols? White ones I'm referring too. Obviously can't tell by the curled feather........ that's a big duh..... lmao! I couldn't help myself but I'm sure you know what I mean. Chickens you can tell by tail feathers and comb. Thanks. Shoot, we need spell check.... ugh.
