I just purchased 6 chickens 3 Rhode Island Reds and 3 Black Sex Links. One of the Rhode Island Reds has laid 2 eggs since we have had her home, but in the last 2 weeks has not laid anything. The other ones we have had for about two weeks, but have gotten nothing from them. We feed them a supplement that goes in with their feed, but it hasn't seemed to work. Do they have to get used to their new home or what? We are new to all of this and don't know a lot about their behaviors yet. I searched in the forums, but didn't really find anything. Can you help?
