That's not nearly enough information Robin
How big, how many eggs, busy pattern, no spots in the aliens, 1000 gram adults, just laid eggs adults?
So many factors go into what an "adult" female goes for.
Also I see people advertise 1000 gram "adults" all of the time. I'm not saying yours were, just stating "4 adult normals" for $150 ea doesn't give enough information as to size, previous egg counts, looks, etc.
