<human>: Give me the gist of the text in a nutshell

To start off, this fuck up didn't happen today but rather yesterday. About 3 weeks ago I purchased a few chickens and ducks from my local tractor supply. Just 4 chicks and 4 ducks. somewhat anxious about have livestock for the first time, I took what proper precautions I needed to in order for them to survive and for the past few weeks things had been going great. I had read online that ducks of such young age shouldn't get wet unless they are dried off and put under a heating lap. When it came time for me to clean their areas I had taken the ducks into the house to swim in our tub so that my daughter could watch them. She is only about 10 months so she loves watching them. After their little swim, I drained the water but decided to leave them in the tub since they were a bit older than last time while I finished cleaning their pen. About a half hour later my friend goes upstairs to find that two of the ducks are convulsing and what looks like trying to break-dance while the other two repeatedly stomp on them! We quickly grabbed up the 2 that looked fine and put them under the lamp then quickly tried to dry and take care of the other two.  We managed to nurse one back to health but one was not so lucky. Now I have 2 ducks, a special needs duck and chickens.
<bot>: Tried to let my ducks go swim, fucked up and one seized to death right in front of my 10 month old.
