We have a turkey that was given to us. She lives with our 20-ish chickens for a couple years now. She gets moody every now and then. Lately, she is quite aggressive when we go in the coop to feed/water/open. She has pecked us and she generally fluffs up and comes at you. I use the feed lid to guard myself and gently kick her away when necessary. Other times, she's quite like a pet who loves to be pet and will literally close her eyes and fall asleep in happiness. She usually starts getting grumpy around Thanksgiving (do they know?!?! We aren't going to eat her) but this time it's worse than ever.
Has anyone else experienced this? Advice?
