I'm still trying to get my little dove, now 42 days old, to eat seeds. He is interested in them, but if he pecks at them for more than about a minute he will start to gag and throw up a little. Is that... normal? He seems perfectly fine otherwise, and eats his formula/seed mix from a syringe without issue. He is still gaining weight, and is currently preening, fluffing, and thinking of flying onto my head.
