Ok, I have read through ALOT of posts about bators. I am on my way to get a thermo/hydro w/probe combo. This is what I put inside the wiggler, right? Do I leave it in there all the time? Explain it sllloooowwwwwly to me-pictures are even better! Also, in missprissy's tute on making a breadbox bator, she had in the photo a humidity gauge of some sort and the temp/hydro w/ probe. I'm off to buy them but If I don't need both, please for chickens sake, tell me so I can return some of this stuff! Thanks!
