I built one similar to this and I had to make the light guard taller where I could mount my thermostat to the wire and let it pull heat off the wire to regulate the temp. It still varies from 99.5 to 100.2 not really bad though. I also use a 40 watt light instead of the 25 watt. I have one vent...
I have washed every egg that I have hatched. I just wiped them with a damp washcloth and dried them off. Last batch hatched 12 out of 15. Don't think it really makes a difference.
I built a chicken tractor with an enclosed section to lock them up in. I had a light in it at night and on warmer days I let them out to walk around a bit and then close them back up at night.
I'm no expert but that shouldn't make a difference unless it has some type of disease or mold in it. As long as you cleaned it I wouldn't think that would be a problem. Hope you the best of luck sorry I didn't know anymore to tell you.
I also have a hot water heater thermo on my cooler bator. I had to mount it to a piece of wire to tie the thermostat to to get it to read properly. It is designed to get temp from metal around heater.
I have a small tupperware bowl that I sit under light to get the humidity up. If it gets too high I open the holes in top of my homemade bator. On the day of hatching I have a spray bottle that I mist through a hole in bator to raise humidity even more. Hope this helps it works for me.
I hatched these babies out on 4-10-2009 and all seemed well until tosay. I found one this morning spitting up what appears to be blood. What can I do to save the rest of them?
I had a chick born this past Friday with the top of his beak twisted to the side. Bottom part is normal. He isn't growing as the other 10 are that was born at same time. Any suggestions on special feeding or just let him try and learn to deal with it?
