    is there a reason why all my large eggs aren't fertile but all my smallish eggs are?
    if I crack open the small eggs you can see it clear as day, but the large ones hardly have a speck in it
    im sure kellogs dosen't know who lays the big ones

    My guess would be that one of your hens lays a small egg, and one lays a large egg, and the the rooster is only managing to get the job done with the one laying small eggs.

    Maybe if you provded some more info.......

    How many hens? Are they of different breeds? Number of roosters?

    Good luck figuring it all out.

    I have a cuckoo maran roo with 4 cuckoo maran hens and 5 Delaware hens, 5 red hens and a leghorn hen
    I'm pretty sure He likes his marans hens best because those eggs are all good
    I get that he probably has too many hens to keep up but I still find it odd that only my smaller eggs are fertile.
    even my large white egg is no good

    The most logical/probable guess is that he is not breeding all of the hens.
  5. for my "mixed" flock of ducks that free range we have a mallard drake and mallard as well as cayuga hens... the mallard drake refuses to have anything to do with the cayugas, he prefers the mallard hens.. though when we had his father he would breed any of the girls... so some males prefer females that "look like" them.. others don't care.
