First… I’m curious to see how much handling and work you do with your weanlings and yearlings??? I typically like to handle them regularly - i.e. haltering, leading, picking feet, standing quietly, intro to tying, grooming, taking for walks around the property - simple, elementary stuff… as I also believe they should learn to be horses, just grow up, and not be over tasked at this age. I know some breeders turn them out with their age groups and handle them only for farrier/vet care until they are ready to start them. And then I know other breeders are cross tying by the time they are a year old and lunging. I try to stay in the middle somewhere.
Second… This method has worked for me with numerous young ones - modifying as needed for each individual of course. BUT… I have one filly (10 months) who is a love bug one minute and a sassy little brat the next. I imprinted her at birth and have handled her daily since. I’ve tried the “do more” approach with her and I’ve tried the ignore her “do less” approach. I’ve tried many different methods! Nothing is working for this tough cookie. Although there are many things she is doing very well with, she still is not great about leading, is “ok” about her feet, she will often pin her ears at me when I ask her to move away from me, and when really pushed she will even kick. I have never had a young one like this. She is not scared of anything, is super bold, and already tries to push around her babysitter aunty (who is an alpha mare herself), and her fellow weanlings/yearlings (who are doing great with their “manners”). Any thoughts on a difficult young one???
