HELP! I have a guinea hen that is desperate to brood and hardly ever comes out of her nest. She even hisses when I come near her in her nest and freaks out when my dog comes near the fence. Little does she know that two of her eggs are wooden dummy eggs, one is hers that I take ASAP, and the other belongs to my Barred Rock hen who sneaks in during the day to lay (I take that one out ASAP as well). This weekend I'm adding 6 more nesting boxes in the chicken coop so everyone can have their own spot. My question is this: when she's finally able to be alone, should I get some fertile guinea eggs for her to sit on? Is that what she wants?!? Of our three guineas, we're still not sure if one of them is a male so fertility is a question. And the eggs she lays have extremely hard shells, so if she does lay fertile eggs, will the egg shells be too hard for them to hatch? I'm new to guineas and how they behave. Could sure use some sage advice here!!! Thank you!
