Today I got two Pekin ducks from Tractor Supply. One of them is acting strange. The duckling's one eye looks crusty, and it has trouble keeping it's eyes open. They are always half shut. Also, its cheeks look swelled and it keeps it's head close to it's neck. Also, it doesn't walk or swim normal like my other one. It also sleeps weird, like on it's side. 
I feel really bad, and were just gonna see if it's still like this in the morning, do you know what could be wrong with him/ her? I am worried
. They have food and water, and they're under a heat lamp.
