Dh was out cutting the grass when he almost ran these over... they were in our corn field. Dont know whos they are or how long the have been there... The chickens havent free ranged in a couple of days, plus I havent found any eggs in the nest boxes that look like these. Our 5 guineas run our yard and hand out in the corn field... so do you think they look like guinea eggs? Our guineas our 21 weeks, when do they start laying eggs?
