Hello, I know I probably sound insane... But I have this huge male brown rat that lives on my yard who is very timid and sweet, and my dad wants to kill it. I don't see it as a threat to my chickens as it is clearly afraid of them, and it is quite friendly for a wild rat. I tossed some bread to as I was treating my chickens to it, when I spotted the rat and it hid in the shed... I sat down and tossed some bread to it and it came out of hiding, stared at me for a minute as if judging my trustworthiness, then ran off back into hiding after grabbing the bit of bread, seemingly deeming me trustworthy enough to take food from me. I am hoping on catching it so that my dad won't harm it as he wants to poison it, I am hoping to keep it as a secret pet if possible. It has no signs of any illnesses, clean sleek fur, shiny bright eyes and is quite plump and very alert and active.
