I have a pair of Cayuga ducks that will be a year old in July. I had been collecting her eggs but then thought she had stopped laying...Well my son found her nest with five eggs in it...and she is pened up but had some ferns in there and made a nest there. HOw long should i give her to see if she will set on them...We are in Florida and not worried about the cold at all...pleae help i do not want to lose them if she doe not go to setting on them....
