My Mallard Daisy laying diff color eggs? Is this possible?

[ldrwnorman47]

I have one mallard female and 2 pekins males in with 40 chickens. They all have gotten along until recently when I went on vacation and came home to a bald mallard. They had pecked all her head feathers out. I rescud her and put her in a cage by herself to rest up, she seemed relieved. I went to check her this morning and there are 3 blugrn eggs and a brown one? Is that possible? Any input would be fantastic. I didnt even know she was laying !!!


Thanks

Well, if she is isolated, it *must* be possible!!!
