I just noticed that a couple of my roos and hens have some scaly legs I've had to treat for this before and I've done so by washing legs and coating with vasoline and I'll probably do the same thing - which stinks because I've got a *MUCH* larger flock :-/ But, I got to do what makes everyone happy and healthy, right! So... I've read back through the forum and searched the net but I don't really see anything about treating the coop/run - which I've never really done. My flock is free ranged part of the day and part of they day they spend in their run and coop. We were getting ready to do a little redesign of the coop but I want to make sure we aren't just adding more breeding grounds for the scaly leg mites by doing so. I know free ranging is going to make them prone to these critters. I'm weighing the pros and cons here. I don't want to keep treating for these critters but I want everyone happy and they really like to roam. Is there something that I need to put in the coop? DE isn't really available in my area (unless that brand new TSC carries it). I don't want to have to do an egg with draw if I don't have to. I'd like to keep it simple. Also, it's been really wet out here with all the rain and storms. Does that make a good breeding ground for these suckers? I've got 17 chicks that will be added to the flock in a couple more weeks. I want to make sure I'm not setting myself up for failure here. TIA ETA: My coop has concrete (used to be part of the garage) floors and I spread a thin layer of pine shavings on it.
