I am thinking about adding to my small flock. There are some pullets and full grown hens in another town. I want to get a few more as a rescue operation but also to add to what I have. These birds act healthy but they don't look as nice as mine. Their combs/waddles have been pecked at. They are not as bright red as my hens but more dull/dark red. They smell bad. They pretty much live outside. Their coop is way too small for the number of birds on the land. If I get a couple or three, I am going to quarantine them for at least a month or more to make sure they are not sick. They are free ranging birds and pretty much have been fending for themselves. I doubt they have had good protein/nutrients or medicated feed. During the quarantine period I'd like to get them fat and happy and healthy. While they are quarantined should I feed them medicated feed like medicated chick starter? Or is there something else I could feed them that would be good for them while they are quarantined. Some medication that they may have missed out on as chicks? What else should I be looking for in the quarantined hens? I don't plan on eating any of their eggs while they are quarantined.
