Welcome, it's so nice to meet you! I'm from NC myself and this year started raising chickens and well... chicken math took over and the addiction began! I hope you enjoy it as much as I do here...I have met many wonderful friends and learned SOOOO much from many of the pros. Jump right on in, you will feel right at home in no time!
I purchase most my products from largo feed thats also where I purchased my chickens.
As for the coop I have done a lot of online research.
Ive found having a good foundation of sand on the bottom works great to decrease moisture. Whatever design you use make sure itll keep coop dry.. moisture and chicken poop stink.
Does Largo Feed normally carry chickens or only at special times like Easter? I've gone there several times but didn't see chickens. Also, do you buy your chick feed from them? Do you mind posting a photo of your coop, I'm researching the types of coops for this region - some coops I've seen for this area have 3 sides with the fronts opened while contained in a netted/hardware cloth pen.
