In the Northeast it was 0 degrees last night - working with the ducks today I noticed one of my girls limping. Picked her up and her feet were frozen - I looked at all the other ducks - geese and chickens, everyone else is fine. Question: is frost bite fatal? will she lose one or both feet? should I just cull her so she does not suffer? Never had this problem, first full year with ducks. Also only giving them water in tall heated buckets so they can't get in.
