My Pekin duck has not went into the pool in 4 days. Usually when I change the water they go crazy and take a great bath but she didn't even do that. It snowed the last 2 days and she went out with the other duck and lays by the pool for awhile then goes back inside to eat and repeat until dusk then they both come inside. I have been putting them on the back porch since a predator got our drake. She got some bite Mark's that I cleaned and put antibiotic ointment on. She is eating well, behavior normal except for the pool thing. I did get a pond de-icer and they didn't like it floating so I took the styrofoam out. Any thoughts?
