Greetings everyone, recently we moved our hens into a fenced in wild land pasture while we grow a pasture of oats for them in their old run extension.. there are ferns, and wild honeysuckle and black berry bushes in the wild land pasture.. and they have a lot of bark/soil, which is full of grubs and worms… 3 of my pale pink egg layers, now are laying eggs with out pigmentation. They lay a white egg… the egg strength is good so they dont need calcium.. but wonder what could cause this.
