I think the rules are still pretty simple. Offering 6 purebred eggs. You can swap once a week per breed you can offer. Make the end/beginning of the week at Midnight on Sunday. So you could theoretically offer your 6 Leghorns at 11:00PM on Sunday, and if someone took them, you could offer them again on Monday. It could get a bit complicated offering 2 or more breeds at the same time, but it could probably be done, as long as you kept track of what was taken in a given week. I still think we need to give 24 hours on any swap, since people interested in the swap will be checking in once a day, at least (ha!!), but sometimes can't check in until the evening, or the morning, or whatever.
