Do not beat up on yourself, you are a fine person just as you are, and you love your animals, and as a wise old person once said **** happens, move on.Thank you for all the tips, everyone. Apparently, the issue got taken care of and we don't need to involve the police anymore.
Sorry about the late response - this kinda got put on the backburner as I had to euthanise one of my original Polish hens yesterday morning and then almost had to do the same to another of the Polish hens that same evening. I'm pretty broke up about it since she was my favourite and because of the reason she had to be euthanise. I'm kinda feeling like I am not capable of taking care of this flock because of my TBI and the issues it presents for me. I just feel like I should have caught this issue sooner and she shouldn't have had to die.
