I really need to vent to chicken people about this... My sister is up visiting with her 4 kids...You can already see where this is going.. She has a little one that is probably over a year old now, and of course, she found my incubator. As soon as the came, I told them the importance of not touching ANYTHING in my "chick room" or I was going to be crazy angry about it...Well guess what? They have been doing good so far, but then today issues started...I started a summer job today, so I checked it before I left, when I got home, and a few times after (I have chicks hatching today). When I checked it this morning, since the AC is on in the house, temp was a little low, so I turned it up a little when I woke up, and checked to make sure it was good 2 hours later before I left. I have been putting it off, hoping that we could turn the AC off, but no such luck, so I just turned it up a 1/4 click (I know my incubators better than I know myself sometimes...that was more than enough time to wait.) I checked it when I got home...And the temp was at 107!!! She told me that I have chicks running loose in the incubator, so she went to check it, and the kid must have "bumped" it to turn it up...Its an LG so you know how the thermostats are! This incubator has been running at the same temp for the last 3 months...There is no chance that it would randomly jump to 107 for no reason...Especially considering I hurried and turned it down, and it went right back to 99 and is still holding strong. I have no idea how long it was like that, but luckily, the already hatched chicks and the chicks that had pipped were ok. Later, she told me that the kid had tripped over the cord and pulled it out...I was FREAKING OUT! Luckily it was only my thermometer that she pulled out, but still...So I figured I would check the humidity while I was there...I look at the front of my incubator, and it was COVERED with pink marker (you can imaging what was going through my head at the time)... I ran down, blood boiling, and told my sister about this...She just calmly said "oh, I know. She did that a while ago"...I was SOOOO angry!!! Seriously! They are guests in this house, and she cant keep track of her kids after I told her, and her kids, not to touch it...But to let her go as far as marking up my incubator, and not even disciplining her for it??? I am still angry...I told them the next time my incubators get touched, I'm going to get very angry and actually yell about it. I know, I know...You all are saying, well, you shouldn't have left your incubators in a room that a small kid is in...But you know, I have them on a 3 foot high table, tucked in a corner where no one can see them. The better question would be, why was she leaving her kid unattended in a room that I said was off limits? GRRR...Anyway, sorry, I had to get the out before I went crazy about it... I'm sure you guys have experienced this more than once?
