Wow he is fun colored! Looks like you'll have a ton of hair! I'd like to make him a touch deeper, but he has a good lower third on him. I like that he doesn't have that typical shorthorn head(can't stand those), looks like he'll have good bone and foot on him too. Good luck with him!
The melatonin works. If he won't eat the pills in his food get a syringe mash them down into powder add water and try to give it to him that way. I've never seen ace have any adverse effects, but as far as I know that's a drug only obtainable from a vet. Good luck!
