One of my hens finally started laying! I think that was the longest 22 weeks of my life! the problem is she's not laying in the nesting boxes. She's just laying in the corner of the coop. Is there something wrong with the boxes that I build. I have noticed that some of my other chickens are actually sleeping in one of the boxes at night. They are younger birds only about 15 or 16 weeks old. Is that maybe why she's not using the boxes? they are about 12 deep x14 high x18 wide so they should be big enough. Are they too big maybe? I've lined them with about 3 inches of pine shavings. should i be using a different type of bedding?
