Recrooster asks you to find all 13 Roosters hidden around Yara. They are fighters for the cockfights at Montero Farm, and a map you can buy shows where every one is.
1. Buy the rooster map. 2. Go to each spot and pick up the rooster. 3. The trophy pops when the last one is yours.
Grab the roosters while you clear each region, since four sit in each of Madrugada, Valle De Oro and El Este. The map is worth buying if you are missing the last one or two, because it saves a lot of searching.
