So I've been saving up a special pile of eggs to feed back to the hens today and I cooked about 20 for them to eat. I've got 8 girls that are laying right now (out of 20,every day there is another laying getting used to the cold) and one rooster for all 20 hens. 75% of the eggs I cracked this morning were fertilized (from the past 5 days), and my question is: can my roo really be getting that busy? That's six girls. How many hens does a single rooster normally mate with?
