Hello from Sydney, Australia. I am a brand new chicken owner after inheriting them at our new house and am throughly obsessed with the chickens (4 white leghorns (Henny), 3 Australorps or Black Orpingtons (Betty) and our favourite, Isa Brown, (Mildred). The chickens would be between 1 - 3 years old. I have a few questions and haven't bee able to see the answers anywhere?? Firstly within the last week one of the white chickens is being picked on and pecked by the others. Never seemed to happen before but the other chickens are quite aggressive towards her and are hurting her. She is struggling to get near the food and is socially isolated, has wounds on her head and seems sad? Why? It makes me a little sad.... Meanwhile the big black Betty seemed broody but... at first she just stayed in her box and we were frantic she was sick however after doing some reading it would seem she is broody however now she has very fat scaly feet? She is very noisy and vocal when near the other chickens (seems quite the strange chicken) and when we go to feed her every morning she screams out of her box, squawking and running at a million miles and hour. All very weird? Lasted 3 weeks or so. She does leave her box every now and then but otherwise always there? A few of the other chickens may also have this scaly feet but not as bad? Overall in the past week the chickens all appear to be a little strange (it is the start of our Spring), are laying less, being a little more aggressive and the pecking order has definitely changed.... plus above. What should I do? Also the chickens run is very large ( approx 30 metres) but is mostly dirt with some trees and weeds and low shrubs. Should it have an actual grass floor or some particular plants? Any other must do tips to make my chickens happy (toys? etc). Thankyou so much - I eagerly await your tips and advice.
