My baby horse was born 2 weeks ago and weights a total of 18 pounds. is she too young for me to enter her in the horse fashion show?

If it is just 2 weeks of age, then it is younger as according to statistics, 3 year of Horse is equal to 6 1/2 year of Human baby, & they don't develop enough quality to participate in a competition at that age

Also, normal weight is 100 pounds for a baby horse, so if it is just 18 pounds, then you should increase it's calorie intake, as it is very less than the normal ]

Hope this helps!
