The mass of the quail was around the same as a small rat. Zero mess unless you count a little bit of down. I fed a twice thawed one once, and no problems with that either. Cleanliness wise it was better than rats. There is almost always a couple drops of blood with rats. No defecation issues either.
The babies should be nice. Almost no chance of normals I have a single 1/64 chance of getting one. Almost everything I am breeding has Super or ALS involved. Lots of white and purple snakes on the way. Many enchi combos and a few highways. Sadly no Super Gravel or Lavender Super Phantom this year which is what I really wanted.
