Hello. I just adopted 2 geese from a waterfowl rescue. They said they were likely a mated pair but that they didn't check the sexes. The geese are best friends at least. One is a toulouse and the other is a buff back. The toulouse is bigger, agressive, and dominant towards people while the buff back is smaller and very shy. I assumed the toulouse is the male but I have seen the buff back mounting the toulouse in their water bucket. I have seen the toulouse mount the buff back too but I've seen the opposite (buff back mounting toulouse) happen more. Could they both be boys? Both girls? Also, it has been really cold at night and the rescue said they should be fine. They have been fine so far at 17F but it is going to be 0F in a day or two. Will they be okay outside? Another question: How do I teach the toulouse to stop biting me? I found a post that said to hold their beak closed until they stop fighting each time they try to bite but each time I let go of him he bites again and he also has some scratches on his beak and I am afraid I am somehow causing these scratches. Is there any way to tell the age of my geese? Thanks!
