Hi all, I am fairly new to raising a flock so bear with me. I ordered 15 day old chicks and all 15 have survived. They are now 13 weeks old. The coop itself is approximately15 x 10. we should have a run completed by this weekendwhich will be an additional 16 x 12. We are using arena sand in the coop, this seems to be working well for us however if there is something better let me know. I use a clam shell digger to sift through the sand several times a week just like you would do cleaning the litter box.. Also using shelf liner underneath the roost on the dropping board that I clean five times a week. Poop is everywhere and it kind of freaks me out since I have a phobia on the worms and parasites. How do I treat the coop and the chickens to keep them healthy and happy? Do I need to put anythingin the sand? Do I need to worm them? How do I keep my chickens free of parasites? I have read a few books, lots of blogs and love this site but there's so many conflicting answers that I just get confused. Thank you for your patience and your knowledge.
