I hatch in plastic egg cartons with the bottoms cut out for air flow. Under the cartons is shelf liner. Keeps the hatcher cleaner, and gives the chicks good footing.Without cartons , the first hatched chicks roll a lot of unsecured eggs around, so those later chicks drown in their shells. Just when they figure which way is up, somebody yells, "Touchdown!" and sends them rolling.Same here - I have eggs going to the hatcher tomorrow, and have had the same problem Jeff described, I am definitely going to try this too - will be good to compare notes.
I used 3 Sportmans for years. Now I use two GQF styrofoams. One has a fan and turner. The other I use as a hatcher,just has a fan.They work great. I do clean,and disinfect the hatcher in between hatches.I spray the inside bottom with TILEX. This gets into all those cracks. Rinse, and use an Oxine solution to disinfect. Then sit in the sun until dry.The lid is wiped down with a cloth soaked in Oxine also. If you smell anything in an incubator, you have a bacteria build up problem.
