Hi! I have three pigeons, and they all are highly anxious birds. One is slightly aggressive, and none of them like people. I want to try to train them or just help them become less anxious. One of them, the youngest male pigeon, is being picked on by the other birds, and he can only come down from the roost when the others are sleeping. All of them are quite picky eaters so I can't really find any treats that they like. If anyone has any tips it would be great if you could share! Thank you!
