Sigh. Basically 6 or so weeks ago we had a power outage. A neighbor of mine (I didn’t know well) was incubating eggs. I have a generator so she asked if I would incubate her eggs. Me being a sucker for animals said of course! Well here we are I’ve got 4 chicks about 2 weeks old. I went by her place, she’s gone, like picked up and moved. A neighbor across the way said she moved to Pennsylvania. Anyway I don’t know the breeds or anything at all about the parents of these chicks. Before I introduce them to my flock, are there any precautions I should take? Vaccines or such? (I don’t vaccinate my own chickens or chicks). I do not want to introduce diseases or something to my flock. Any suggestions?
