There is a female mallard duck living in my backyard. For a few weeks, the male and female would stand by the pool and wash off in the water. Now, the female has built a nest in the backyard (and she has laid several eggs) and she occasionally swims and takes a bath in the pool.
Please let me know if I should be treating the water any differently. I've kept the chlorine level a bit higher than usual. It is a salt walt pool. Everything looks clear and tests within range. After the duck takes a bath, there is some dirt on the bottom of the pool, but it cleans off by the end of the day with the pool sweep. Should I add any additional chemicals, shock or chlorine? Is there is a problem with the duck using the pool? Thanks for your help.
