I've seen a bunch of coop designs on here which is helping me and my buddy move along at a good pace on our project. So I see that under the foundation of the coop, beneath the hardware cloth cage, I have seen people laying down what looks to be black plastic which is followed by sand or gravel. My yard at the moment is just dirt. I would like to achieve proper drainage and easy maintenance for the run. For the coop I was gona go with pine shavings and a vinyl floor. Total estimated size 12'x4'x6' Coop 5'x4'x4' 10 chicks comin in next Thursday. I've had a blue front amazon for the past 13 years, I have dealt with all types of bedding, and I know that parrots are different. The best method Ive found is to clean it daily. So if ya'll could, advise me on what would be good for the run, and what would be best for the coop. Cost efficiency, and lightest maintenance in mind.
