24 June Evening Update: Tonight was the first time they both left the nest together. Martha, who we did not see out at all yesterday, was first but Stella followed about five minutes later. It appears Martha is more committed to this project than Stella. Anyway, they both had showers, took a swim, ate, and ran around being super broody and noisy. They both had mealworms, but Martha nipped at any duck that came near her (not at me though). I quickly checked the nest while they were off it, and there appear to be five eggs. Stella went back in first (maybe 15 minutes out) and then about 10 minutes later Martha went back in.
