I've been hatching hundreds of chicks a year in styrafoam bators my husband made me. We recycled big chests like the kind medications come in to TSC. Well, they've been working alright but the pc fan never really circulated the air effectively leaving hot and cold spots and the styrafoam itself would begin to break down and get stained and blah blah blah. It's been a good run but, I was ready for an upgrade. My husband is the kind of guy that says, "why would you buy that when I can make it?" meanwhile.. years go by and you still didn't make it so.. I started hunting and found this guy http://customincubators.com/ I bought the 3 tray cabinet with hatching tray. It does not come with trays but will fit hovabator turners and was less than half the price of a sportsman. I also upgraded to two fans and two lights. When I opened it, it was so beautiful, I could keep it anywhere but, that's not what's important right? So, I fired it up yesterday and the temps have been holding in EVERY corner of this thing. Those big fans are what does it. It's at 100.4 degrees across the board and hasn't budged a bit. It's so easy to control everything the top hatch in the picture opens and that's where the water wells go. I leave mine slid over just a bit to allow for ventilation. The fans suck down from there so it works perfectly. Rusty only had time to make me one tray last night so, I won't get to fill it til tonight. top hatch view of hatching tray... and my little squirts who were very interested If anyone else is interested in getting one, the incubator maker is giving a small discount to BYCers. Pm me for more info. I'll keep y'all posted as to how my hatch goes!
