Hi, I would love to get some sebbie geese. I understand that they have to be kept separate from chickens and dogs. I have met a few and they were very friendly. Here are my questions; Are they all friendly? Or do you instill this in them when young? If you have multiple ganders in a small flock, will they fight like roosters? Do they eat a lot compared to chickens? How much space do they need? How many eggs do they lay approx in a year? And how many are fertile? Are their eggs difficult to hatch? I have done a lot of searching on BYC for this info and couldn't find definitive answers, so please forgive me if they are duplicates. Thank you for your help.
