Incubating is really much more involved than it seems.
I set twenty four eggs (purchased from a hatchery/shipped via mail) into a forced air styro bator. I joined BYC the same day, thought I had read everything on the subject in books, magazines, online, etc and prepared as best as I could. Temps and humidity were terrible to try and maintain. Ambient temps around bator were never stable and varied by thirty degrees daily. Candling went and appeared great on days seven, fourteen and eighteen. Forgot to apply some of the remedial steps and probably over did some of the more complex items. Long story short, day twenty one produced a chick. Day twenty two, another chick, but she was a struggle and syringe fed for two days while she fought for her life. Happy to report, both are doing well now.
Still determined, balance of eggs remained in bator until day twenty six with no more hatching. Today was a heart breaker as they went into the garbage can.
when you candle it, go buy some paraffin.
Dipping one end (the narrow one) of the egg will help slow the movement of water through the shell.
Unfortunately I heard this after eggs A, B, C, E, & F hatched. D (the sole porous-shelled egg) was a half-formed dud. *sigh*
I learned that sooner (rather than later) all critters become my responsibility here.
That we really do have BIG snakes around here.
Too carefully look in the nest boxes before sticking my hand or face inside (see previous line)
That the only day I don't check feed and water (no matter what was done the day before) is the one day it all runs out, gets tipped over or otherwise made unuseable.
Beginning to learn to watch for that glazed eye look when going on (and on) about my chickens to non-chicken people - so that means everybody I know.
When a website says "WARNING: addictive" they really mean it.
