I currently have 5 Welsummers, 7.5 months old, only 1 of which is laying. We're getting a little tired of only having freeloaders, so I found a nearby farm looking to get rid of 20 red sex links, and they've agreed to sell me just 3. They are 1.5 years old, the woman says. They are only $4 each, so as long as they give me eggs at least until the others pick up, I'm good. I understand that red sex links may not lay as long as other breeds. My coop and run are big enough for about a dozen birds, as I always plamned to add 2-3 a year, to replace the older ones. So, my question is mainly what should I look for when I go to get them? How do I pick out healthy birds? Both in general of the flock, and any tips for picking the right 3. I've never had chickens before my current flock, so I'm new to this! I do have a plan for integration!
