I have a hen sitting, she started last tuesday 17th may, she started out with 5 one broke. I removed it of course and today cleaning out nesting boxes and placing more bedding in hers i noticed she had 3 more. Is she laying them or the other girls? I have a total of 15 hens 1 rooster and 3 pullets. 2 of the other original eggs have old yolk and bedding on them and would it be alright to wipe them off with a damp cloth?
