At what age can a male guinea mate with a female? We have had a female for over a year. Last year she would lay eggs in various places, or several in one place, but never stayed with the eggs. When she started laying this year, she would do the same thing. She was always around, blending in nicely with our chickens and ducks, leaving an egg here and there. Suddenly she seemed to disappear. We found her yesterday, sitting on a nest in some tall weeds behind the house, with 6 or 7 eggs. She is very protective of the eggs. Today I took her some water and food (although I'm hoping she does leave the eggs for food and water...I just never see her) and just trying to put the items in front of her, she was very intent on pecking me...over and over. She has never done that before. We did get three keets earlier this year....I don't remember exactly when (should have written it down!), and I'm wondering if one or more might be male and are old enough to mate with her, so she is sitting on fertile eggs? I guess I'm reading more into this than I should, but she is just acting so different with these eggs, and I can't help but wonder if she knows something I don't? rhoda_bruce, can you recommend a good book about guineas, to read? I hadn't thought much about them one way or the other, but now I'm starting to get more interested in them and would like to know more. I'm leaving the guinea with her eggs, keeping my fingers crossed that a predator will not get her (we had been keeping her penned at night) while she is out with no protection. I could move her into a place that would be pretty safe, if I thought she would continue sitting on the eggs. I have a duck that has done the exact same thing...always would lay eggs but not stay with them. About the same time the guinea started guarding eggs, the duck is doing the same thing. She doesn't want me anywhere near her. She is on 9 eggs And as with the guineas, we got a baby duck earlier this year. The older one is a mallard, and the younger one is evidently a Rouen...already bigger than she is. I'm wondering if he is old enough to fertilize her eggs, and she knows they are fertile? I can move her too, since she is easy for a predator to get to, but wonder if she will continue to sit on the eggs if I do. Any ideas or thoughts are welcome. Thanks!
