2 of my muscovey girls have gotten into the canal and we made a ramp, and then over 2 days in the freezing canal one came up the ramp and then the next day i couldnt find the other one and my dad came out and saw something down the canal and he said thats her alright, and i said look shes coming to us, and then she took a turn onto a different canal and i was SO sad, until i heard a splash and she came out from behind the banana trees in the shallowest part of the canal all dry and warm, and for another night she was in the canal because we couldnt catch her and then finally we got her, and people say it isnt cold in florida, but tell me its not cold when the temp is like in the 40s with the wind chill 30s and then in the water way below freezing you feel bad for your ducks being in the water and you are so helpless that finally you go in the canal in some mud boots at 6 am in boxers and a shirt trying to loure your duck into netting range, IT WAS SO COLD, and she found the safest place and warmest so i think Izzy just found a nice place to rest or go through the storm with because if i were a duck and i got lost, i would probably go under something or find shelter of some sort! So good luck with your search and i really hope you find her, we all understand what you feel! We are all crazy duck people too! c:
