They're getting luxury then! Our tube gets a bath in boiling water now and again!
They can be finaky like that, one wonders and it's disowned! Or you get the ewe running between the two in a panic!
Our best adoption technique is to split a feed bag open, pull the single into the bag, so the juices are collected
Then marinade the adoptee in it. Squeeze as much juice off her lamb and onto the other as possible.
No harm to either fill the adoptee with colostrum os tie it's legs to make sure her lamb gets a proper belly full.
The stronger lamb will empty a ewe out in minutes!
