Hi all, I've been on this site just for fun and when I built the coop for my own chickens last summer..However now I have a big challenge ahead of me. I'll take some pics tomorrow,,but I have a big job ahead of me at my work. I work as a manager of a small local zoo. The zoo has a very large "aviary" that is barren and has about 6 wild turkeys (both male and females) and some assorted ducks (not sure what kind yet)..This poor space is very neglected and needs a major overhaul. Funds are minimal. I am up for any and all advice!! I need tips on ground cover, feeding, overall structure,etc. I am unsure of the exact lenght of the space. I'm guessing 75-100 feet long and about 6 feet deep and 12 feet tall. The area is a long rectangular (fenced in)shape, open on top in the center (I am hoping to add some bird net over the top to prevent anything from getting in), with two walk in spaces on each end. There is a ditch that runs the length of the space to act as a "river"...this usually gets minimal water flow, and if raining floods out. The ground is dirt. Right now there is a very tiny dog house in there wich one hen duck has laid eggs. I would like to add ground cover, but unsure what to use--options I have that are on hand are mulch donated from landfill, cypress screened mulch, sand, peagravel, crushed stone. We have lumber if I need to build some "huts" or houses for them I'd like to add a "pool" ,but it would have to be simple and not utilize a pump for this season due to budget restrictions. Also, what do you guys feed your turkeys/ducks? I know that pictures are worth a thousand words, I'll take some tomorrow and post. thanks in advance!
