I've been told by a breeder and keeper of exotic birds that he doesn't use one because they are a waste of money. He has used one, and prefers not to. He said turning doesn't have to be carefully turning every egg. He just takes one hand and rolls them when he thinks of it. Usually twice a day. His hatch rates are much better than mine.It turns so slowly, I don't think they could would get caught.
Now that it's been brought up, I'll probably get a keeper stuck in it...
BTW, I have had much better hatches before I got the turner.
There is alot to be debated as to why, but that is just my two cents.
