I bought a mare and foal last fall. The foal was just a week old when I purchased the pair. Mom is 30.5 inches and so is the sire. The lady I bought them from did file an AMHA stallion report, but never paid the fee, so I have to get the filly DNA tested. My question is this: The filly is already 31.5 inches at a little over 5 and a half months old. I'm thinking she will go oversized, but wanted to see if anyone else has had a baby like this. Do some grow really fast at first and then slow down? Or will she keep getting taller and taller? Either way, she is a real sweetie and I'm keeping her, but I wondered if it was worth all the hassle and expense of getting papers on her if she will go oversized anyway. Thanks for any feedback!
