Would be interested to see a whole picture of the lamb. Did discuss this issue with various breeders at Sedalia. My guess is that ewe is shorter bodied. The quest for moderate ,fuzzy, round sheep has lead to many short bodied , shorter hipped, compact ,"moderate" sheep. Same amount of guts and muscle, jammed into a frame that is 2/3 rds of what it used to be.
That is what makes this fun.
I like sheep that are longer than tall. Longer bodied ,wide based ewes have more gut capacity, but also may be later maturing. That is not currently in vogue.
As one breeder commented at Sedalia. "Some guys will tell you about how many dollars thier flock has generated, or how many dollars each ewe has sold lambs for. Other will tell you about the ewes and rams they have sold to other breeders that generated for those breeders. One type breeds sheep that breed on. One type is " making" sheep the sell for high dollars.
You can "make" this ewe productive , or you can breed sheep that breed on.
I choose to try to breed sheep that breed on, and breeding on means culling hard for defects.
I am not sure that my values are of the type it takes to "make " sheep that sell for high dollars.
I hope that I can breed sheep that breed on and sell for repectable sums of money. And that would be any breeders goal.
But I know that if I buy a ewe from someone that starts throwing defects, I likely am culling and likely not going back .
She will likely be fine and generate for you.
