I need a bit of advice. In the spring I cleaned the coop and removed the old nest boxes with the idea of building new ones. A new flock of 25 barred rocks were put into the coop. Unfortunately between work and being sick, time got away from me and the hens started to lay about 5 weeks ago without any nest boxes. As a result they started to lay on the floor and burying their eggs in the pine shavings. About two weeks ago, a new series of nest boxes have been added. The problem is none of the hens seem to be interested in laying in the boxes. The nest boxes are a duplicate of the old ones with the added feature of a sloped floor so eggs roll away from the hens and into a collection area so I can get them (had a problem in the past with egg eating in one flock). There are 6 in total and they are 12h x 12w x 15d. The boxes are 28" off the floor and each has a plastic egg inside to encourage laying. Any ideas on further discouraging floor laying and encouraging laying in the nests?
