Hi, I am hoping somebody can help us identify whats wrong with one of our ducks, we have 4 ducks, 3 female and 1 very frisky male, the problem is with our oldest female (approx 2years old), when we was checking her over we noticed that on the middle of her back is a very sore patch.
We routinely spray for mites and have even used a blow torch and 'fired' the duck house to make sure there isnt any mites hiding! we have also treated the ducks just in case! Daisy (the problem duck) feels a little lighter in weight, though she is eating well, and she has at times distanced herself from the group

she looks a little bit tatty compared to the others as well!
Could the sore patch be due to the frisky behaviour of our male duck?
If anyone can help we would be so grateful.
