My female turkey is a year and 1/2 old. She has always been perfectly sweet to everyone, Whenever I enter fence she immediately would come over and lay down next to me and let me pet her especially stroke around her neck. When my husband would come in to clean coops she would always be right behind him doing the same thing. I assume always wondered if she was "presenting" herself to us which I saw on another thread. She would never peck anyone except once in a while jewelry. This last week or so she changed. We cleaned coops yesterday and she didn't even come lay by us When I enter fence she comes over but not real close, doesnt lay down and I can tell less comfortable with me petting her. Today I went in and she wasnt aggressive but she bit at my fingernails..which are painted but then she grabbed hold of my hand and took a minute to let go. Do they become more aggressive in the fall? The only thing different is we had let one of my chickens hatch some eggs and got 4 roosters they had all been sleeping in her coop with her because they didn't fit in my chicken coop. We had to round up the roosters last week and get rid of them. I don't know if that could have anything to do with her behavior.
