My experience with chickens has been pretty trouble free, but ducks are a different story. The one was of course not bringing them home without a place to stay. Ended up living in a plastic fence pen for a week, which had a roof that was too low. Second thing in that pen was burying a tub to swim in at ground level with three week old ducks. No one drowned like you might think, but it was filled with crap and mud by the end of the first day. Had to use a smaller bucket to bail all the water out till it was light enough to get out. Mistake number three, after they were moved to their bigger pen and not making sure there were no holes in it. One night something spooked them and one girl rammed her head in the hole and was a bloody mess. Number four after that was thinking she could stay outside with a less than ok bandaging job on her head and not get infected. Ended up with a full grown duck in my bathtub for three weeks.
