I am new to all of this egg incubating. I just bought some fertile eggs. Now, how long do I actualy have before they have to go in the bator? If temp fluctuates say 2-3 degrees up and down will they still hatch. I just purchased an absolutely beautiful coop and cabinet incubator along with some hatching eggs from backyardchickens.com that someone on here reffered my friend too. My hubby almost went with the incubator plans instead of the cabinet from them, but hubby isnt so handy, shhhhhh......lol so I talked him into the cabinet one they have on the site. For the price you cant beat it. Now I have to just get the whole incubating with temps down, I already wasted a dozen eggs trying to use those styrofoam ones, I couldn't get the temp right on that either. Any help would be appreciated.
