I am planning on getting 2 shipments of chicks because the variety of birds I want won't all be available for one shipment. My first shipment will be 8 birds on September 6th, followed by the second shipment of 6 birds on October 17th. I have read a few threads about integration of chickens to a flock but I haven't seen too much information on introducing baby chicks. I realize it will be 6 weeks difference and the size will be noticeable but what do you think I should do for a brooder? Should I use two different brooders altogether or should I craft one large brooder and run some chicken wire down the middle so they can see each other. I guess there's just a lot of factors to take into account, will the 6 week olds even remember the baby chicks when I move them out into the coop, or will it just be integration all over again? Also one last side question, my birds will be little chicks during the winter months, the coldest it ever gets around here is in the 20s fahrenheit. Will it be safe to have a brooder outdoors with a heat light? Any tips on keeping a brooder warm and secure during the winter months?
