I currently have a flock of 14 hens. I have been wanting to enlarge my flock, and I do have chicks coming in april.. but those will take a while before I can add them to my flock. So I went to a ladies house and purchase 3 very nice hens for my flock. I was able to see and be around her entire flock, all of which look very healthy, clean, and nice. The three hens I purchased are very nice, no visible health issues or anything to assume they would have any sickness. But to be on the safe side. I have them quarantined in a separate pin , last night after bringing them home, I dusted them thoroughly with diaotomaceous earth, I also have the food grade which I added to their food last night. My question is , since I was able to see the flock... how long should I quarantine? do I still have to quarantine for a month?? How can I tell if they have any sickness? what should I be looking for health wise. And they are laying , so how long should I wait before eating the eggs?? this is my first time bringing in full grown hens to my flock so ANY information would be helpful.
