Sorry I'm not instantly responding. I'm putting my critters to bed in between messages. I'm in Ontario Canada so it's 6:00 here. How are they looking now?
I gave up using rat poison because I decided it was cruel to the rats, but when I was using it I put it in a cake tin. Lid on during the day when pets and chickens could get at it, lid off at night for the rats.
My chickens ate a cube of mouse poisoning (not a warfarin base, so Vit K wouldn't help) I was told by the chemical co. that there wasn't much to do but wait and see, but it is supposed to not kill secondary animals, such as cats that eat the poisoned mouse. Anyway, that was last Summer and they are all just fine! Whew! Now I only put the poison in those feeder things and have it weighted down with a heavy brick. Hoping yours will be just fine too! If they are ok today, I would guess they made it!
Just to clarify,if any pet has ingested rat poison,feeding vegetables high in Vitamin k does not contain enough to counteract poison,you need Vitamin K1. Also poison often takes days before effects show up. If your birds are fine,then they probably did not ingest any or a very small amount.
Best advice is to call a animal poison control centre(they operate 24 hrs)or vet.
