I want to share a somewhat funny story. Last year I got a new dog (Kai) to keep my other dog company while I was at work. She is a good girl and does well with my chickens. Since I live out in the country all animals run free, so I leave the gate open for the chickens to free range. Not long after I get Kai, I started noticing eggs out in the yard. My hens are strict about laying eggs in the boxes. The eggs were undamaged but I didn't know what to think. After about a week of this, I saw Kai go into the chicken coop and she had her mouth closed but it looked odd. So I go out there and sure enough.. she has an egg in her mouth. She would just bring them out into the yard where she likes to hang out. Not play with them or eat them. As much as I love Kai.. shes not allowed to go into the coop anymore.
