I have to first say both are gorgeous. What a sharp colt and what a gorgeous mare. Maidens are so scary. You did such a great job. I am just so proud of you for doing all you did.
I have had so many things happen here, but am learning so much from this post. i almost wonder is he a little bit of a dummy foal, as we had one who is awesome now, but boy what a scare. It was like he had it all at birth and 12hrs later the lights just went out. But with Dexamethazone and banamine he improved. He figured it all back out and he is a normal healthy beautiful colt, but he circle and licked the walls and just didn't get it. But he is fine now. And may add only 3 weeks old.
Colts are so reziliant I just hope he has the same luck as mine did. I will pray for him and you. God Bless you. Thankfully he is in the hands of a caring breeder.
