Awesome post!!
Saturation is a big factor in this. I feel it is the major issue we are seeing. I have never seen so many colubrids for sale in my life. Not that it is a bad thing, as they all are beautiful beyond belief! But like you said, so many saw these breeders making some money, and then they wanted to do the same thing, which in itself is not a bad thing either.
Then, all of a sudden, the market has the most colubrids ever! For buyers now, it is definetely a great time. The BP market though is saturated as well, don't get me wrong.
One thing people who breed need to always remember, is that when a customer buys a pair of snakes off of you, and you plan on being around for a while, that customer will automatically become competition. Each time a pair of snakes is purchased, the competition just grows and grows.
Now, it is at an all time high. It is basically again, supply vs. demand. It is also the allmighty factor of how much is someone willing to pay for your animal. While some may be more than happy to shell out $50 for your animal, others may want to offer half. Then, it is up to you to make that decision on how long you want to keep feeding that animal and have it around. Selling any snakes at any time is never a guarantee.
The supply and demand issue is very evident at this time, but it still was around back in the mid-nineties, down here in Tx.. I think it was around 1995, when one breeder was trying to unload pueblan milks at a show I vended at for $20. No one bought them. Nice ones too. So many had them around here.
Another time, in 1996, a breeder behind me at a show I was vending was selling huge, yearling Cal kings for $15. Guess who sold more?? HAHA!!! Yep, he did. So many people had cal kings there, but his were the best bargain. What was really funny was that his breeding stock came from snakes from me years prior! HAHA! Here I am selling my cal kings for $25, and he is smoking everyone there on selling stuff! LOL! Oh well, you have good shows and bad shows.
Heck, one time, the same year in 1996, a breeder walked into a friend of mine's reptile shop, after he vended at a local show, and set a big box of baby colubrids down on the counter, and yelled out, " Take them! I can't sell any of them!! " and stormed out...... Needless to say, my friend was not too happy about this new random box of colubrid goodies.
So, with the case of supply vs. demand, I have seen it for a while. I feel this is a bigger issue than some may put into consideration. If people did not feel compelled to breed anything and everything they buy, there would be less competition.
Attention given to certain species that are not as common is something that can be helpful, in filling in a niche in the market that does not have as much competition. I know that one of my friends who breeds colubrids had his best year in Daytona this past year. He had some things that others don't have.
So, in all, it seems that the colubrid market is going thru a rough time. I say, breed what you love, and love what you breed. Develop backup plans to cover any down times with sales. If you are into it solely for money, you will be dissapointed. View making any money as an added bonus.
