I have a 20 weeks old White leghorn that started laying 3 days ago. She has been laying every 25-26 hours so i have 3 eggs right now. We also have a white leghorn rooster which is also 20 weeks. When can i put my eggs in the incubator and hatch them? And how do i tell if they mate or no. i have 2 eggs in the fridge and 1 saving so i can put in the incubator when i have atleast 7. 1st egg = 36g 2nd = 38 and 3rd = 40.. Should i be hatching them this early or should i wait?
