I have a roughly 7 month old columbian rock hen that has been laying for at least a month or more. The last four nights she spent in the laying box after she lays her egg. I have been removing the eggs from under her (sometimes some from other chickens too). Even after I remove the egg she remains. Each morning she comes out and goes about the day. She will go back in occasionally during the day...She gets very upset and "protective" when I take the egg away. I am only 5 months into raising chickens so I am new... is this signs of being broody or since it has been getting cooler is she only there as an alternative to the perches?? I don't want chicks at this time of year... getting cold. Will she get past this? If she will be broody in the spring that would be great. She has had a bit of a runny nose too.... but does not seem to be bothering her. Any ideas???
