I got the idea from my friend in the UK just modified it a bit to suit my need. For these chicks I did a small version of a coop to accommodate them while they grow out enough to put with rest of flock.
This is one great little box you have and the top accessible makes for an easy way to get in an see what is going on inside assume
I do believe you have more then exceeded the average coop
I was mistaken in an earlier post, Julian was a Jan 15th hatch so will be 4 months this Sunday, not 4 & a half as I had posted prior. I normally keep the feeder at 16 inches, just have it raised here to show how tall he stands.I will try to post a link for a video of my flock.
