Please, I need help to understand this expression in the following :
... - "I'm not selling the calf this year, not to you or anybody else," Rachel said abruptly, forced to come out from behind the currant bushes, her annoyance rising in a hot flush in her face. "So get about your business."
- "Oh, so that's that, is it ? Retiring, I s'pose, and living on what's in the old stocking, like Griffiths Ty Sych. Or better still, rearing the old calf to be a bull ! Rachel Evans, Pant y Brill. One-Ex Bull !"
And Teimoth laughed in his most jeering way at his own joke.
"You old blockhead ! It's a heifer calf th cow's got this year again, as usual. And I'm going to keep her because her mother's getting old"....
Thanks to you !
The bull calf has been or will be castrated.
However, as the calf is a female, the joke is on Teimoth.
