Choose healthy animals.
Know your genetics: know which morphs are recessive/dominant and which are line bred, for example.
Choose your best animals that represent the closest to the result you're looking for and breed them.
Think carefully about how many geckos you want to produce. Producing fewer geckos can limit your breeding possibilities somewhat, but you also won't burn out and won't flood the market
Read everything everyone else is writing and copy/paste whatever seems memorable so you have a document of all the important stuff
Crested genetics are up in the air, you can place 2 harleys tgether and get tigers, flames, dalmatians, patternless. They are not like leos where one + one = two.
The best way to have an idea on what your geckos will throw is by knowing your geckos background, gecko A from petstore A and gecko B from petstore B is like a crackpot, you never know what you will get. But if gecko A came from red parents, and gecko B came from red parents, your odds are high of having red babies. And the farther back the morph goes, the greater odds of producing that morph.
Some things just simply hideout, both parents and grandparents can be clean, but they can also still produce a dalmatian, it is one of those genes that simply pop up.
And when breeding you want to buy the best you can afford, if the best you can afford is low end, then it isnt advised you breed as people look on several levels and not just one: color, contrast, head structure, and crests (crests and head structure are not the same thing). Two average geckos are going to produce a bunch of average geckos with maybe an outstanding one here and there. THe market is flooded with average geckos, so you want to offer the best you can that is above average.
Sometimes you can make a compromise, like a female with poor to average crests and structure placed with a male with good to great crest and head structure, your babies are more at to have good to average crests. But if the female has poor to average crests, and is simply just an average gecko (lacking on nice color and contrast), she should just be best kept as a nice pet. And the same goes for males, remember it is quality not quantity and there are plenty of average geckos to go around.
There is plenty on the web for good advice on breeding, I would suggest reading over at Pangea or Repashy as they are crested gecko forum, you will find all the great reading you should find over there, and one great read on pangea is the "Supply and Demand" thread, so do a search over there and I highly suggest reading it, its long, but gives you tons of into on how to's and what to consider.
hey guys, i was just reading this thread out of curiosity and while we are on the subject of breeding, would a 12x12x18cm enclosure be a big enough enclosure for a breeding trio, as i currently keeping a georgeous male blonde harlequin with an amazing crest (this is the gecko i was talking about in my previous posts), and i am looking at 2 female crested geckos that are a beautiful red harlequin, first of all (i know you said it probably depends on their parents) but would they generaly give me a few outstanding morphs per litter (is it a litter), and secondly, would having a trio reduce stress on the females as they are not worked as hard, and if it doesnt reduce stress, i have another enclosure that i am currently keeping my male in now, would the females be okay (stress wise) if i moved the male into the other enclosure and kept the two females in the bigger one, would this reduce stress on them, and if so, how long would i have to keep the male in the other enclosure?
Many thanks as always
