Best part is adjustable legs....and yes, will use it again this year, it worked great!
May add some 1/2 HC on the bottom of rack so heads can't push thru.....haven't had that happen to disastrous effect, but it's a possible risk.
Great, thanks for the link and tips on the HC. How many chicks did you raise with this?
