I have a young pair of Dewlap African geese, they were hatched I believe in January or February of this year. They have always been sweet tempered, but suddenly the gander is attacking my dogs and even going after my kids! He started to get "snotty" with me a little, but I just stood my ground and held my 'wings" out to look like a bigger gander and he backed down. This behavior seemed to start at the same time we had a spell of warmer weather, could he be acting this way because we are getting near breeding season? If so, will he stop being aggressive once breeding season is over, or will this become a habit? I would really really hate to have to pen them up, but I simply can't have them running loose if the gander is attacking my children. I had a sizeable flock of geese when I was a kid that always free ranged, and I remember them getting cranky this time of year but I never had one that would actually go for me.
