My daughter has a cow calf pair she's showing. First time we've done this. How long do you all reccomend you pull the calf off the cow before a show? I know I want the udder to have milk in it, but what is a good ball park time? We went out this weekend, and the show was alot longer than we figured, and little baby was pretty hungry and mama was wanting him to nurse. The kids had a work out. Figured this was the best place to ask. Thanks ahead of time!
