Full Feed, I believe is feeding an animal "ad libitum", free choice, which means having fresh feed in front of them all the time. I would not recommend this for a 4-H project calf, try getting the calf used to the ration over 2-3 weeks, feeding at least 2 times a day, and no more than 2% of body weight, then after the warm up period, increase the feeding to 3.5-4% total body weight.
Make sure you provide plenty of available forrage, hay, grass etc. and lots of clean fresh water.
