I wrote a reply to this post last night when the internet dropped out and I couldn't repost. (Grrr!) I was lucky enough for some good friends of mine to incubate a clutch of eight woma eggs for me a couple of months ago. I was unprepared (yes, rather stupidly), as I didn't sight any mating whilst they were together and I thought that it had all been unsuccessful. Anyway, I would have been more than happy to either pay them cash for their trouble or give them part of the clutch, whatever they deemed appropriate for their kindness. When they took my eggs they said they didn't want any form of payment, which I was appreciative of, however, I also don't like being a freeloader and so when I picked up the hatchy I gave them a nice bottle of wine for their help. I think that it's unfair to expect something for nothing, even if nothing is wanted in return. That said, I also think that if someone is incubating eggs for a mate and would like some form of reimbursement that it should be settled upon at the time of the eggs being taken/delivered for incubation.
