Congrats on getting chooks and on the Eglu! It's a very nice way for city folks to get started with chickenkeeping in their own backyards. Don't knock yourself for getting it... I doubt ANYONE here will, either.
Make no mistake, though... this might be your first coop, but it will by no means be your last. At the very least, I see a future for this Eglu as a grow-out pen.... LOL.
