I don't think it's the greens, the blacks, the blues or oranges and I don't even see any morph market? Where is it?
I hear from a big rodent breeder the very opposite to what you're saying. Perhaps it's because I live on the opposite side of the town. LOL
You should look harder Jag variants have taken over the high end of town and are now commanding the top dollars instead of what was traditionally the place of greens. The top end market hasn't gone down its just shifted focus. And in time the jags will be replaced by something new.
Granted the low end stuff like macs, bredli, coastals etc are now in such over supply that breeders cant get rid of them. But hey we all have adjustments to make if we want to survive.
In terms of the rodent business most cant keep up with demand and have a continuous backlog of orders despite prices having gone up significantly in the past 3 years. What happened to the $1 weaner rat?
