I am new to owning chickens. I bought 10 little chicks from the local feedstore in March. I know they were a mix of males and females. I had one rooster (Ronnie) start crowing about a month ago. Now all of a sudden I have 2 more crowing. Do hens mimic roosters? Please tell me this is so. I hate to have to get rid of my new little pets. I love all my chickens and don't want to part with them.
