Today I was given 7 new adult hens (buff Orpingtons and RI's). I was not expecting them to be in such terrible shape... the biggest one has pecked the rest nearly bald and when I put out food it was like piranhas on a steak. Feeling sorry for them, I put my own 4 BO's in their coop on the other side of the house and let the newbies out to free range a bit in the backyard (grass, playground mulch and a garden) for an hour. Uh oh. I forgot that you aren't supposed to do that. So, now my BO's are stuck in their coop til I find out what to do, and the others are safely quarantined on the other side of the house. Is it possible to lysol the whole backyard??? I can probably do the bleach/vinegar on the playground mulch, and my garden is basically empty right now except for a few tomato plants, but bleach on the grass.. not good. Thoughts? Or just let the sun do its job for a few days? The other question is, do I need to quarantine them before butchering them? I had planned to keep two and eat the rest.
