We have 7 Silver Laced Wyandottes. I found one dead earlier today. From what I could see, there were no signs of pulled feathers, blood, red spots, etc. I called soooooo many places and only 1 vet offered to do a necropsy on a chicken, but were super pricey! A few months ago, the county tore down a house across the street. Since then we've had a rat problem....thankfully outside! I found 4 dead ones within 2 days about 2wks ago. After talking to my cousin-in-law, we feel maybe the neighbors are putting rat poison out and perhaps a rat left some droppings in the coop and she pecked in the wrong spot. ( It is bothering me to know what she went through and felt prior to dying if this is the case (( Any suggestions please!!?? I have decided to toss the eggs that we have gotten from the coop over this past week....rather be safe than sorry.
