I had to discard 42 eggs that I candled at 10 days and found to be clear. I had bought these for $1.50 per dozen(guess you get what you pay for) I would have been better off eating them!!!! I reloaded the bator with 50 eggs, 3 EE and 47 RIR. I bought 4 dozen RIR eggs for $4 per dozen from a gentleman I had used in the past with great hatch results. and the 3 EEs are from our own stock. you would think 50 eggs is enough but no another of the people I buy eggs from had 1 dozen + partridge Cochin eggs for sale and I bought those too so now I have to buy another bator in the morning. Now I know I'm hooked!
