I have done breeding loans with friends that I have known for more years than I have been breeding -- these were all loosely done and came out rather well. Mostly they would bring over their females and when they ovulated I'd give them back. On occasion I have lent out my normal females for breeding as well.

In 06 I had a dozen or more normal females that were ready to breed and really nothing to breed them to -- I was working strictly with recessives -- so I entered into an agreement with a well known "good guy" that I had bought from before. I sent him 5 of my females -- close to a year later I get them back -- of the 5 I sent there was one clutch produced mostly normal males - one girl "died" but he wouldn't tell me when or how when I asked that he send her back for necropsy he said he'd already disposed of her -- but he did send me a "replacement". The other 4 that he sent back were all scrawny and 200 or more grams less than what they were when I sent them the previous year.

Needless to say I won't be sending out any more snakes on loan.
