Sorry if this is in the wrong section. I have two chickens, (used to have three, one died), that are about 4 months old. I have to get rid of the rooster, so that'll bring me to one. The other hen has never been alone. I was wondering whether to buy a pullet around her age or get a chick, raise it, and then introduce it. Which one would be better? And then onto the next question. How would I go about introducing the new hen? I heard that the older hen might kill the new one. Thanks for your help.
