Okay so i have 3 RIRs that are about 7 months old they are laying well and very sweet and friendly....well that is unless you catch them right before a lay, they can be very crankey. I have 4 new little chicks that are 2 weeks old i plan to try to add them to the flock in about 2 months. I am not fully sure on how to integrate them without too much of a mishap. I dont want any birds left behind. Heres my plan....we have a coop right now comfortably fits about 6-8 full grown chickens, but! we are in the process of building a bigger and better coop which will easily fit 12-15 full grown chickens after adding the 4 new babies we will have 7 chickens total....okay so my plan was to not integrate them until the new coop is done so that the older girls wont have dibs on the territory. Then i planned to maybe take one full grown girl at a time for about a week and give them supervised visits with the little ones, then if that goes well, let them ALL graze together and then put them all in the new coop..... I dont really know if this is good planning or not i need some insight! i have looked up what to do and there are MANY different ideas on how to do this well but i just want what will make all my girls happy. P.S. the new coop is better insulated and will keep them all warmer thats why i wont consider keeping them seperate in their coops because i dont think the old coop will do when winter really hits hard, which isnt until about late dec. or early jan. for us.
