My 3 brown Africans are about a month old and just beginning to grow some feathers. We call them Linus, Lucy and Sally. I let them out to free range with all my chickens during the day and at night I put them in a pen with my smaller chicks. (I plan to put them in the duck pen when they are older, but I don't trust my ducks not to hurt them yet) There were 10 little roosters sent with them for warmth and they all get along great together. Those little tiny chicks can do what ever they please and the goslings will absolutely not bother them. The other chicks that are a little bigger have gotten feathers pulled by the geese on occasion if they get too close. On the other hand, the big chickens have picked on them some, and when they get close the goslings take off running and whistling like it is the end of the world. But not today! I came outside this morning after letting everyone out and the geese had wandered into the big chicken lot. Several big chickens had them surrounded and I was about to go rescue them when it was like all three goslings had a light go off in their heads at the same time: "Hey, we're as tall as these suckers are now!" Next thing I know they were standing their own ground getting right into the face of each chicken one on one. Every chicken backed down too. It was the greatest thing I've seen since my Golden Retriever fetched his first stick.
