My first year breeding I picked up 7 Proven breeder females and a few single gene female hatchlings to grow up. I had a couple of double gene males and I wanted to start breeding a small number of animals. i managed to get 4 clutches which was a nice start to get my feet wet and figure out pairing, breeding, egg setups and incubation, hatchling care etc. My first clutch got me hooked with 12 perfect eggs and 0 normals. 1.1 yb, 2.3 pastels and 0.5 pastel yb. I kept 4 of the Pastel ybs which will be bred this year. I've gotten to the point in which my collection has grown with more morph females and so now some of the normals are moving to new homes. I will of course hold on to a few of the big girls 3600 and 4100 gram females are always nice if you want to try and prove something out like you said. Also nice when you pick up a beautiful male Banana Mojave Yellowbelly too. Maybe 30 is on the high side, but everyone's collection is different.
