Stevo,
Pretty easy.....15 per day, and 2x the daily limit equals 30 you can take home per person.....So, you're allowed 60 doves in your possession in 2 days of hunting for the two you....Just to be safe....I'd have them in 2 separate bags.
Like Kevin (Waterdawg) has stated….Cut or brake one wing off, pull breast up and off the rest of the torso....Put on ice.
ps....Make sure you ALL the doves out of your vest the 2nd day....An old friend of mine (76). Got a citation a couple year back for having one dove over his limit....It was from the day before.
