I think the Eglu is adequate for 4 egglayers (think med-lg breeds as most egglayers are...RIR, sussex, barred rocks) or maybe 6 smaller hybrids. My goal is also movable, plastic for easier cleaning and disinfection, easier access. I live in a 4 season climate but will also not be doing a full tear down in the middle of winter. The poop tray cleaning is appealing for that time of the year. My Eglu will be sitting on a 4' x 8' raised bed (rotating annually) within a 10' x 10' chain link enclosure with a lid of chain link panel covered with hardware cloth and a tarp in the summer for shade. Also, we allow some free ranging on 1/2 acre when we are home to supervise. Pretty sure the rare bear or coyote we get around here could break into an Eglu, but so far they always come during the day and we have learned how to prevent the snatch and grab. But the more common danger here is owls, raccoons, skunks, and snakes. The Eglu looks sufficiently tight for those predators at night. Not one of our wooden coops has stood up over time to those predators. Wood rots, decays, cracks, needs to be replaced regularly. Or, if you make it sturdy enough to withstand the predators, it is too heavy to move. Constant cleaning and disinfecting degrades wood walls and floors, even in our dry desert climate. I've spent enough on wood and hardware over the years to buy a Eglu many times over. I'm almost retired and want to make my chicken hobby a bit easier to maintain in the future. The Eglu will also keep a limit on the number of chickens I will be able to house ;-) .Waiting to build a few more raised beds first this year, then time for an Eglu Cube and some Fall chicks.
