I totally agree with this! This is why I just did a bunch of trades completely rebuilding my breeding collection. Now instead of having 70 + animals that will produce normals, single and some double morphs I have only 20 animals that will produce NO normals and baby's with up to 6 morphs.
The days of doing well making lots of single morph babies are pretty much coming to an end. This has always been true but more so now then ever before... It is about quality, not quanity.
