OK, I went on holiday for a week leaving behind my two young Copper Stars who were getting friendly and let me stroke them, and very nosy, trying to get out of the door to the pen everytime I opened it, and 3 timid ex-bats who ran to the other end and hid.
I left them in the care of my MIL, who I believe has spoilt them rotten, giving them fresh veg every day, possibly every hour, talking to them all day long etc.
So I have come back to 5 hens who sprint to the door every time I walk near them, shouting away at me, who peck at my hands and feet if they come near the pen, let alone if I try to put my hands in, and just now one of the Coppers leaped into the air with a little flutter to peck at my fingers as I leant on the pen.
I preferred it when I could open the door without being seen as food - is this normal happy hen behaviour, or do I have to establish myself as boss. Cats are so much easier to understand!
