I came home this evening and as I always do looked in the bird house to check on all of my feathered babies. I found my male welsh harloquin duck with his head flipped back and he was throwing it from side to side. I immediately grabbed him to investigate and somehow it flipped back in the normal position. I put him back down and by the time I turned around he had it backwards swaying again. I grabbed him up and brought him inside and put him into a cool bathtub and gave him electrolytes and food. He immediately started playing and acting like nothing was wrong. Can anyone please tell me what the heck happened? I went back out and grabbed my girls and threw them in too just in case.
