I have a pullet who has been laying about 7wks could she be going broody already? She is in the nest box every evening and we take her off and put her on the roost. Went up to the coop just now 7pm and she is in the box already warming up that plastic egg. Well left her there because I am not sure it is the same chicken. It may be another trying to lay. All mine look alike I will take a marker up with me tonight if she is still on the nest. That way I can tell her from the others. I sure hope she is not. Just tell me she is to young. March chic.
