Pure Bred Langshan Pullets

Sun bathing after a dust bath.  Langshan hens and roosters are large, placid birds with feathered legs. The hens lay dark brown eggs and rarely go broody. I have four roosters (all different breeds) and the Langshan rooster keeps well away from the other three - he's a lover not a fighter.
Bella is not well and had a visit to the vet clinic this morning.  She has a lung infection and is on anti-inflammatory medication and antibiotics for a week. Kennel cough is doing the rounds and I was worried she might have caught it but the vet assured me she doesn't have it.
