I went out to the chicken house last night, DH got 2 new white guineas, full grown, locked them in the chicken house, we raised 40 guineas in it until 2 weeks ago when we took them all to a sale... never lost 1.. they had been in there for 2 days, well, there was the white guinea on the ground against the back wall under the roost, it was moving so I thought it got stuck, so I tried to pull it out, it moved more, weird movement.... then I grabbed its feet and pulled, something pulled back.... I got it out and its head was eaten and neck all most all eaten, a big gash in its back.. I shined my light where the guinea was, saw a tunnel, not really big, but not small.. I went back in the house for a better flashlight, put the guinea 3 feet from where I found it, went back out less than 5 minutes, it was back by the wall, I pulled it out again, and shined my light, there was a big rat!!!! AHHHH!!! took the other guinea out of the house an locked it down and put poisen out. I HATE RATS!!!!!
