We have a Serama who refuses to lay in the coop, and sneaks off to lay, then goes broody. The first time, we found her in a planter bucket after she didn't come home one night. She had 7 eggs. Then, she began laying under the tarp covering the hay bales, but we found her eggs before she could brood them. THEN, she started laying in an overturned planter bucket filled with straw, right by the run. I figured, great, problem solved. Not so fast. I knew she was sneaking off, but I couldn't find her nest. Then, like before, she didn't come home at night. We found her under our storage trailer, wedged between the concrete block, and floorboards, in the insulation.
If you enlarge the photo, you can see her black tipped tail feathers. My 8 y/o son had to crawl under the trailer, and pull her off, pecking him viciously all the while, and gather the 7 eggs she again had laid!
So, how do we trick this chicken into laying in our run/coop? Although her eggs are small, they are tasty, and we hate to lose them since she is actually a decent layer. She is also my daughter's favorite chicken, and it is only a matter of time before a predator finds her at night when she goes broody.
