I think a group of breeders should get together via email, and determine how the data would be recorded, and all do like 2 spider x spider pairs each. No one would have to take a terrible financial hit buying housing and feeding mass amounts, and as long as the data is well recorded all of the results could be compiled together. If you got 10 breeders here on BP.net, that would give you at bare minimum 20 clutches to study. Plus ive seen people around here claim theyve known other breeders for upwards of 10 years. If you can maintain a business relationship for that long I dont see why youd lose touch once you started a long term experiment like this. Just my 2 cents = P Im not really established enough to do the experiment myself, but I am curious like you wouldnt beleive.
