Thanks for that. I'm pretty sure he's not fed - I wasn't there when he was born but I think I was within an hour. None of the tests looks like it's been sucked, they're a bit muddy. Based on my limited previous experience, the kicking away by the mother subsides once he's had his first feed. He seems to be losing his persistence, possibly due to being cold and wet. Mum is very restless and wandering around all the time, and he's gamely trying to follow her. But if he has a nuzzle, she either kicks or moves on.
She's never been tied up before, but I could give it a go - she's fairly docile, and is OK with me handling the calf. I just wandered if the powdered colostrum was worth doing so he at least gets something, and then I can worry about getting him latched on to the udder?
