Buff Orps are known to sometimes go broody but usually not this time of the year.
Maybe a couple of options. Gather all those eggs and make cakes, pies, custard, all the healthy meals you can come up with. Once you've done that and had the dog lick the dishes clean crack open a decent but cheap bottle of winr, maybe a Barefoot merlot, and contemplate the calendar to try to decide on what broody season may be as you enjoy a good meal.
Another option since I think it is mostly calendar related is start talking in an Australian accent, especially about going walkabout. Look up the proper wardrobe and maybe hang a few kangaroo posters. Instead of merlot, maybe a shiraz. Channel your inner Mel Gibson, Nicole Kidman, whichever Aussie you feel you can best channel and convince them that they are south of the equator. Down there it would be the right time to go broody.
