My chickens are 16 weeks old tomorrow (YAY!!) and I've noticed some of them losing tail feathers. I know that less hours of daylight and molting can cause a disruption in egg laying, but can them being colder also do that? When do I know when to turn on their heat lamp in their hen house? And because of the molting and few hours of daylight does this mean I'll have to wait longer for their first eggs? Some of their faces are getting redder, but as far as I can tell no squatting or egg song yet, but I just would like to know what I should expect. Haha now that we're so close, I'm so impatient! Thanks!
