I'd like to draw on your collective resources to help me with weaning our 4.5 month old colt. We have two full grown horses: colt's mother, Zuni, and 19 year old NSH gelding, Winslow. We have two separate paddocks (half acre each) and run in sheds for both horses. I am wondering if you all have opinions--know you do, want to hear 'em--on the safety of gradually moving colt, Ishi, from Zuni's through the gate to Winslow's? Is this crazy? Winslow is a pretty gentle, levelheaded horse but confidently dominant. He's tall: 16.1 HH. Otherwise Ishi'd have to live alone with no shelter until fully weaned. How long will it take till he's completely weaned (her bag dries up, etc.)? Thank you!
