Okay...so long story....Yesterday my neighbor's dog killed 2/3 of my flock. Very sad. He was very nice about it, helped clean up and got me new hens. I'm worried now that getting new hens is going to do more harm than good. He got 10 hens from 2 different sources. I don't have a place to quarantine. I don't know what to do. How risky is it not to quarantine? They are all layers, so all grown and about the same size. So I have 4 original, then I think 6 from one place and 4 from another. We already stuck them in the coop, just tonight after it was dark. I don't know what to do. (As far as quarantine...is the damage already done?) And please be nice to me...I'm still sad about the whole thing. I'm fairly new to chicken raising. I'm worried.
