Lately Pony has become very mean to Soda. If I hang up a treat for them in their cage, Pony will not let Soda touch it. He also always takes the food bowl closer to the middle and makes Soda take the one closer to the corner. If Soda takes some of the treats or eats from the "better" food bowl, then Pony will peck at him or pull his tail feathers. I feel really bad for Soda. But, after their fights they will groom each other and give each other birdie kisses. I noticed this happen when Soda had to stay at the vet's and Pony was alone in his cage. Does Pony think Soda is an intruder?
