I have a flock of 21 hens and 2 Roos they are 21 weeks old. The first issue is they are not laying yet the roos have not started crowing. I'm not sure if it is a slow down due to season but all of our other flocks typically have laid by now. My second issue is a sick hen she is just puffed up and slow moving. We separated her from the others last night to watch her. Any advice appreciated!
