Today I was filling the duck pool and noticed that we suddenly had two white leghorns. The three leghorns were sticking together like glue so she's obviously been here awhile and I've just been mistaking her for our other white leghorn! I have a large flock of about thirty birds and they're all healthy beasts and the new one seems quite healthy as well. I just... what? Should I even bother trying to quarantine her at this point? She's obviously been accepted into the flock and i think she's been here for 5-7 days.
