I ordered a pair of ducklings from the local farm store and while they are certainly all black like my older Cayuga ducklings, these two definately have helments. One more so than the other. I'm a first time duck owner so while I'm fresh into the pool, nothing I read or saw indicated that Cayugas have helments. Will try to post pics if necessary for identification. What's the overall concensus?? Are these really Cayugas?
