Hey guys, I just recently got two pekin ducklings, and they seemed to be doing great. But now all of a sudden, they aren’t eating as much, drinking as much, and have started this weird head twitch. It’s strange to me, as we have had ducklings in the past and I have never seen them do this. They just bob their heads repeatedly, almost uncontrollably. I just want to make sure nothing is wrong with them, and that they are healthy. Thank you!
