I can't believe it! I'm so proud of myself! I know that sounds vain and pardon me for sounding that way, but I have to tell you that I have been dreading this ever since my chickens got sick. Now it's done! I could only vaccinate 25 of them. The others have to wait until they are 8 wks. old. They are 4 wks. now so I guess I'll get them the same time I give the booster to the others. One more bridge crossed.
