I've been anxious to get some fertile eggs of my own and do some hatching. I was trying to decide which breed(s) I like best and thought I wanted to breed some Silver Spangled Hamburgs, which I still do want to do, but need a rooster first.. Anyway, today via craigslist I got a free Buff Orpington rooster.. I just wanted him cause I saw his photo and thought he was pretty.. I like the Buff Orpingtons.. but I don't have any.. But I do have a pair of Buff Rocks and I thought perhaps I could breed the BO with the BR just so I can hatch some eggs and end up with more egg layers, plus I love having little pullets running around, lol.. watching them run around chasing dragon flies is so funny and cute... anyway, these hens are roughly around 10wks old and the rooster is 11wks old and I know the hens should be ready for laying their first eggs at around 20 to 24wks, but what I do not know is, at what age will my rooster start trying to have intercourse with the chickens? When I want to have fertile eggs, I suppose I need to keep the roo and pair of hens together in a run til I get fertile eggs, right? How many times, or days does it take? Suppose hypothetically they're at the right ages now, and he mates her tonight, and she lays an egg tomorrow.. will it be a fertilized egg, or is it the next one? Would a rooster mate two hens in one night so I can have two eggs to hatch together? Anyway, I'm looking for advice and tips on what to do so I can hatch a couple eggs.. Also, if I have fertile eggs in the future that I do not want to hatch myself, do people buy or want cross breed eggs for hatching? What about unknown cross breed eggs? I ask this because if I allow the roo to free range with all the hens, and next day I collect eggs, I won't know which egg is which hens, though I know any fertile ones that he is the father cause I only have this one roo. I'm certainly not gonna hatch every fertile egg that comes my way, but figure, if an older hen dies, I can hatch new ones.. or, I can raise some as meat.. cull and process at whatever weeks old and then hatch new ones and repeat... I suppose cross breed chickens taste just like any other.. right? OH, and also.. I suppose fertile eggs are still edible... are they? Any different than a non fertile one other than a little embryo or whatever inside it?
