When to move hens to the coop

i would make sure they are all fully feathered, and are big enough to fend for themselves. and when you first put them in the cage with the elder chickens watch them closely to make sure there is no fighting going on. they may peck at each other for a little while but they are trying to figure out the pecking order. and there is no garaunty that they will come back to the coop if i were you i would let them all get use to the elder chickens and let them stay together in a pin or under someone watching them and put them up at night untill you are sure they can fend for themselves.
I sure hope this helpes!

 

Also, if you can have a seperate pen for them for a little while, maybe a few days to a week, that helps. The bigger ones can get to know the little ones first, and they are less likely to chase or attack them (the smallest ones and new stuff to the coop are always picked on). I have a portable dog kennel we use.

 

I had to move mine to the coop at 2 weeks when they outgrew the brooder. The coop is insulated, secure and has a brooder lamp which I needed only one night. They're six weeks now and in lovely shape. Mind you, the coop had no other birds in it. It was new ground.
