I have four Warren hens 18 weeks old, on of them Nugget who is very friendly and is always following me about in the garden started to do an odd thing when picked up. The other three try to avoid being picked up but when caught they appear to be ok with it, I have had them two weeks so I'm not expecting them to be sat with me watching TV. Nugget so times when I pick her up she squats down hunches her wings up and makes a chipping like noise. It's like an anxious reaction but she is fine and quite happy when held. They all paper to be happy when held I hold them securely around the body keeping there wings close in one had and stroke them core reassurance with my freehand. Any ideas on why Nugget does the odd squat hunched up bit?
