But I'm somehow missing that wild wide eyed look that says 'I'm so starving you can't even comprehend it'
LOL. I get that one all the time.
The uses of a bottle-reared lamb...
1) Can tame your flock by proxy, that's always great; it's all fine and well to leave them be so you don't distress them, but sooner or later you must handle them, and then what? I prefer all my livestock to be well handled, for their sakes as well as mine.
2) Great practical life experience for children, possibly helps them understand why they DON'T want to rush into having kids of their own... lol! Take those rose-colored glasses off, this is how a baby is: it cries and it poops and it screams and it pees and it cries and it wants feeding no-matter-what, on-the-dot!
3) If it's an unwanted and later unfriendly male, extra-delicious spoilt-pet-flavored meat...
4) Some great breeders, valuable animals, have gotten their start via bottles. Just because the mothering thing didn't work doesn't mean the baby is automatically a waste, in fact, some are special, and worth it. I was surprised to learn that Black Caviar the racehorse was a bottle-bub, off-topic...
Having said all that in defense of bottle-bubs, if I find myself in the position of taking on another charity case, I'll get a second, and raise them in a pen with eachother as company, to avoid the excessive dependence on humans, remind it it's a sheep/goat/whatever, not part of a human herd.
