It has been below freezing here for over 2 weeks now. Some of the surrounding towns broke records yesterday for both cold low over night and cold daytime high temps. So far, so good as far as the duckies are concerned. They have been spending more time in their hut, but still spend a lot of time in their pond. The kiddie pool has been frozen solid for weeks, so I gave up on it. Once warmer weather is here, I will get them a plastic pool and another heater for next winter (the pool I have now is a cheap inflatable pool, I'm sure the heater would melt it). For now they will have to make do with only the little heated pond to swim in. I just have to pump out the poo water every other day and to add insult to injury, both my hoses are frozen. I finally got tired of filling the pond with a bucket, so I brought in a hose and laid it in front of the fire for a few hours on Sunday. Now it's in the basement where it won't freeze again. And I have noticed that since it's been so cold, the duckies won't stand on the snow or ice for very long. They much prefer to stay on the straw covered ground. They get to come in for treats every few days. I bought them a "pack & play" baby play pen. I'll put them in it and give them guppies and mealworms. I know they prefer to catch the guppies, but I won't put guppies in their pond because of the heater. I know the guppies would hide in the "cage" around the heater. I can just see it now...duckies with branded bills from the heater coils. Not my babies! Anyway, I don't worry about the cold. They seem just fine...chubby happy little duckies.
