I am planning to bring home 2 or 3 pullets from a friend at my TSC store. (That is where they originally came from as you may have figured.) She wants to give them a good home and I would love to have them. I currently have 6 chickens. 4 are only about 4 months old. They are all Isa Browns except my roo which is a Light Brahma. The other two are a bit older and already laying. Well, my question is how long to separate them? Is a couple weeks too short? When/if they are placed in finally...should I do it in evening or night hours? They are most likely about the age of my pullets. I will be giving them and all the others at her farm a good look over and wear extra shoes, too. My first batch of chicks caught a disease when I brought home 3 silkies from a woman who breeds near me, so I better use some sense. She knows how I went through that so understands my caution. I love my chickens, but don't want to be afraid to adopt some from a friend. Any advice guys?
