My chicken named Daisy is very sweet, but a few months earlier we found some traces of rats in her coop. We put some traps around her cage (not in it) and caught lots of rats. The smell in her cage is very strong and bad. I feel like the rats population is rising in her coop. She is also pecking at her eggs and breaking them while she is still sitting. Yesterday my elderly mother came to my house. About to take a shower, I asked her let Daisy out of her cage. In the shower, my mother came running into the house yelling. I jumped out and went to see what was going on, and saw that my mother had bit marks all over her. She said Daisy attacked her. All she did was open up her cage. This morning went to let her out. Right when I opened up her cage, she ran out and started to bite my feet and legs. I ran into the house, and saw her stroll right back into her cage. I am afraid a rat might of bit her, or she ate rat feces. She is also puffing out her feathers and walking around. Any help?
