Okay here goes: 1) How do I rid my coop of flies? I've read on here about fly strips (which I'm not comfortable using because of a previous incident with duct tape and a chicken, don't worry, chicken is fine ) and vanilla air fresheners.. 2) How do I keep the heat off my girls? This ties in with question 3) I don't have the materials or the ability to add more ventilation to my coop, because I am a teenager and my father won't help me.. Any tips on how I might be able to ventilate their coop further? 4) How much DE should I use and when? DE is known to cause respiratory problems in both humans and chickens, even the food grade kind.. 5) Any tips on how to get my hens to not lay their eggs on the floor? I clean their nest boxes once a week, and most of them are two years old! That is it for now, although I'll probably think of more later on. Thank you!
