I visited the Duyfken while she was moored in Brisbane River. She's only 25.2m long & 6 across so rather tiny for a merchant vessel. No crew quarters @ all. The crew slept on the deck. Pleasant enough in good weather but it must have been a horror when it gusted & squalled.But sailors kept a surprising number of livestock aboard the great sailing ships. Hens were the most common, since a battery like coop was easier to find room for than, say, a cow. In all fairness, one could say the humans aboard were also housed in something like a battery, if you've ever visited the HMS Victory and seen the crew quarters.
