HI, I have anywhere from 20-30? free ranging chickens on my 1 acre property (no one lives on it--it is all fenced/gated). The chickens meander between properties. They're fed scratch daily, fresh water + day old bread. They roost in trees at night. I'm sure cats, roadrunners and other birds are getting my chicks. Someone on the forum suggested I use hoop coops! What a great idea! Now I ask you chicken experts, I want to build 1-2? hoop coops to have ready whenever the next hen + chicks show up. My last hen + 5 chicks showed up, and none of the babies made it. :-( In the future, I think I can put the hoop coop over them to protect them. Will weight it down or stake it...plus will move it around every few days. I have protected areas too so they get some sun/shade. Any suggestions as to size, material, technique, how to's are much appreciated. Thanks in advance.
