We purchased a Gertrude coop a year or so back. To be honest , I have been disappointed with the design and features of this coop. I have had to undertake several reinforcement actions to the - ends, roof and nest box - happy to share because it is mainly upgrading of hardware and inserting reinforcements to produce a very good coop All that said we added the extra nesting box - which fitted perfectly and appears to be of a higher quality. I would recommend Eggshell-but With the proviso they review their hardware use -should be bolted and not screwed Hinges and the integrity of the two coop ends which I believe require additional vertical supports . Nuff said.
