Hi all. I have never added adult birds to my flock before and I have a question about quarantine. I bought a RIR cockerel and 2 Australorp pullets recently at the Colorado State Fair and was told by the poultry director there that I should only need to quarantine for 2 weeks since all the birds were "vet checked" before check-in at the fair. I did my own inspection of course, and they are free of mites and lice and they appear healthy. It has been 2 weeks now, and no signs of any trouble so far. I read Speckled Hen's flock management guide and I understand that 4 weeks is the usual quarantine period. So, my question is, since the birds were "vet checked" at the fair is 2 weeks sufficient or should I go the full 4 weeks? I went in prepared to do 4, so that's really no problem for me. I was just wondering if the "vet check" trumps that or not. I would so much rather err on the side of caution, but wanted to get opinions from those who have more experience with this than I do.
