A mouse nested in the chicken bedding and moved rat poison into its nest. Dear hubby spread the bedding in the coop yesterday and didn't notice it. I went out today and found a few bright green pellets and then green stool . I don't know how much total they got (I found a 50 gram package) or which hens ate it. The vet said give vitamin K1 everyday for 30 days, is there anything else I should do??? Of course I already cleaned out the coop and run and started the vitamin k. And obviously dispose of the eggs, but that's the least of my concern right now.
