Everyone is different. This is what I do to build immunities and to make integration easier. I might work for you, and it might not.I am anxiously waiting for my order of an assortment of ameraucana chicks from Paul Smith sometime this month. I order 20 chicks (blue, wheaten, lavender, splash). I believe I have everything prepared for them (brooder and a brand new coop). I plan to keep them in the house for six weeks but I wanted to know from the experts about the time I need to quarantine them before I move them to the new coop. I have 9 one year old hens that will be sharing the run with them once they are integrated (there is a partition in the run to separate them until they get big enough to put them together. Will 6 weeks be enough time for the chicks to develop their immune system? although I would like to move them to the coop earlier (maybe about 4 weeks old) but I have read different opinions so I really don't know what is best at this point. 4 weeks, 6 weeks?
I am new to the ameraucana breed (although I do have an EE which I dearly love) so any input you can give me will be greatly appreciated.
I dig a plug of dirt out of the yard where the chickens go, and put it with the new chicks from day one. I add leaves, and litter from the coop every week. I feed them fermented feed and make sure they have ACV in the water.
On sunny days I take them outside in the big coop as soon as I can. As long as it is not freezing, I take them out and let them go with the big birds. I have several big birds that are fine with chicks as long as the chicks are not by food. I supervise and let them run around longer and longer until they are almost integrated. By 4 weeks they are outside pretty much all day with the big birds except at feeding times. The chicks learn pretty fast who to avoid and where to hide and how fast to run. I do not feed with the adults until they are the same size.
