Dumas (my 9yo gelding) took about 3 months to come running for feed and another 3 to be "wanting" to be touched (pet, groomed,etc) and now at 10 months of ownership he is happily sticking his nose out to get rubbed and fussed with. Dumas was "headshy" when we got him and we have done wonders with him. No longer are we having to tie him low to get the bridle on.
Congrats with the new horse. Grab a good book ( I used training manuals and horse magazines ) Go out to his pen/pasture and have a good sit in a lawn chair with a cold drink and read away. He will eventually come up to you and see what you're doing..horses are curious by nature. I would only pet him and aknowledge that he is there when he is close enough to touch without reachin too far. Good Luck!!! He'll come around.
And yes....The people here are the BEST!!!
