One of my extremely skittish Polish hens who is not laying yet just attacked me for moving her off another hens egg! My little Polish gals run when I even look in there direction but this morning when I moved this one she squawked LOUDLY! and pecked at me! What's that about?! Did I commit a serious foul-pas? My gals are 22 weeks old and I am getting 4 or 5 colored eggs a day (no complaints tho! ) so I'm sure the Polish are not laying yet since they lay white eggs. Will a hen set another hen's egg?
