I was on vacation last week and a friend was taking care of my animals for me. Luckily this happened the day I came home or I would have had one dead ducky! I usually keep my ducklings on regular shavings for a couple of weeks and then move them into a brooder with very small wire holes on the bottom to keep them out of the mucky shavings they create. I have never had a problem before and generally the wire squares are much smaller than the feet of the ducks. It's easier to clean and the ducks like the fact that they can make as much of a mess as they want without sitting in it. Anyways, somehow the one duckling jammed his elbow (Ankle part of the leg) through one of the very small holes in the wire. I have NO IDEA how this happened, as the leg was completely twisted and the elbow could not fit easily through the wire. The leg was so swollen I had to cut the cage just to get him out! I expected the worst, but to my surprise, he is completely fine despite his ordeal! I just wanted to warn people about keeping any type of birds on wire! I was lucky, but now I am even more careful. I've never had a problem before, but the whole situation could have been much worse!
