Well I built my homemade 'bator (yes I'm entering the 'bator contest when I get my page done) and I tossed 4 eggs in it to see if it would help stablize the temps. The eggs were from my leghorn and were in the fridge for at least a week. The 'bator temps are stabilized and I left them in just to see if anything would develop. Three of them look like they have a blood ring and I thought #4 was also dead. I looked closer and there is a small mass about as big as a dime. I turned it to try to get a better look and it started to wiggle!?!? Do embryo's move this early? It's day 7. I hope I didn't kill it by tipping it.
