Henny has been acting funny since the turkeys showed up. She's in her nest-box most of the day, but once you rouse her (either physically pick her up or wave food in front of her face) she'll get up, and act completely normal. She'll eat and drink and go outside for a bit and then return to her nest box after I've left. She's not sitting on any eggs but she is making happy chicken noises (that sort of purring sound). She's also stopped laying. She's been pretty regular the 3 weeks we've had her (2 days on, 1 day off) but no eggs for almost a week now. The turkeys are in the chicken coop and they've got a heat lamp which is quite bright, and I think I may have messed up Henneys schedule. Penny is still laying/behaving as normal. Any suggestions?
