So I Am sorta new to raising chickens, I have an assortment of bantams and Dominicks that I got this year. I think they are about 4-5 months old. Today I kept finding random stuff like moss and twigs in the nesting boxes. Is this the hens trying to build a nest or is there a rat or something trying to move into chicken coop to eat the eggs? Haven’t found any eggs the past few days from an older hen I have. Not sure what to do.
