My blue andalusian is now 4 months and is "leader' of the rest. The other four are as friendly as a chick can be. She/he was practically cuddly when a peep, but now very stand offish and eyes me the whole time I am cleaning pens, or anything near the coop. I get the feeling this is a rooster, but not enough evidence of it yet. Is it normal for them to unfriend their owner?
