When you order baby chicks online, you can choose to vaccinate them. Since we are doing this ourselves for a small backyard flock, do I need to vaccinate them? if so - do I just call my vet? How old do they need to be to have this done? Would love to hear peoples thoughts on vaccinating. We have the medicated chick food. thanks! I am soooo nervous about the chicks hatching after reading so many warnings online! We made our own incubator, in candling them we had 8 of 12 that looked good. For a couple days it seemed we could not get the temp about 97/98. Now they are in the 3 day phase aproaching hatch and I can not get the humidity past 68%. If my thermometer is correct. anybody else have this and have things go ok? I find myself checking on them in the middle of the night as well! This is worse than being pregnant! I feel so responsible!
