Hi all, I was hoping to get advice on my hen. In October last year I bought 4 ISA brown hens who were supposed to be 19 weeks old. In December, three of the hens started laying after developing large red crests and displaying 'squatting' behaviours. The hen I'm concerned about still has a small crest that has only slightly turned red and her legs are yellow while the other hens have pinkish white legs. She has never squatted and runs away if I approach her. She gets picked on quite a bit but was picking on another hen before the others started to lay. Is there any reason for these physical differences and anything I can do to encourage her to lay?
