Hmmmm...I'm on the fence as to whether or not to give this a try. One of the Mottled Orps I got from you (Mabel) is the one who went broody. I could tell she was starting yesterday because she pushed the egg she laid yesterday to the front of her breast and just sat on it for awhile. Today she did the same thing with another egg, so I took the egg and kicked her out of the nest, and she complained a bit. Then she went back to the same nest looking for her egg(s). I know that look. I gave her a few ceramic eggs, and sure enough, she is as content as can be. Since she is just starting to go broody, it seemed like the timing might be right since I get the Muscovy eggs tomorrow. If I do go forward with this, how many eggs do you think I should set? I'm getting 24+.
I'd give her 12 and be prepared to switch them to the incubator if she decides to give up. That way you have 12+ sure eggs in the incubator and half the work load for yourself if she does go through all the way.
