I posted this as a response on the chicken side but I thought maybe I'd see if the Guinea people had any suggestions. I am seeing many more differences in the two types of birds than I originally thought... I was all fat and sassy thinking I was doing so good with our birds .... until tonight. I spoke too soon... 6 Guineas had decided once again not to go to the coop tonight when we went to shut up the coop. My husband came in and said "I think your dog got the birds." (When ever the Doberman is "bad" she is YOUR dog to whom ever is being addressed at the time LOL) I went out to see what happened after the Doberman came in from her potty break. They usually stay in the oak tree over the coop and so are not an issue with the dog. This has been an on going problem but they have been fine for weeks doing this despite my efforts to get everyone in at night. I can't chase a bird up a tree This was not the work of the doberman. I've seen what her toys look like. These 2 guineas were mostly undisturbed except they were missing their heads. Add that to the fact that one was in the yard and one in the back of the pick up which I have NEVER seen the doberman show any interest in getting in. 2 down. The others no where to be found in their usual tree above the coop they share with the rest of the guineas and the chickens. I inspected the rest of the yard and saw no birds either. So i go to let the goats guardian dog out to scare off what I suspect is a raccoon. She found a live Guinea under my car and dispatched it. 3 down and not my intent. I never thought about a bird being UNDER my car! She then ran around to the horse lane and found another already dead one. Same MO 4 down . Reinspected the rest of the birds area / our yard and didn't find the other 2. So I head back in the house. About 30 min later I hear a guinea being killed in the east pasture. Not the dog. The bunch of feathers was on the other side of the fence but no bird to be found. Also, there was not a bunch of feathers laying around where the other birds were found dead. So #4 may have been eaten by something else. So I put the guardian dog back with the goats. I checked the coop several times and the birds in there seemed undisturbed. The chickens are so good about going to their coop at night. Which is awesome because their job is to eat bugs and stuff around the yard and give us eggs. The Guineas were bought as tick control. Hard to let them roam the property for ticks if they won't come in at night and are dinner for a raccoon. What really irks me is it is such a waste! ONLY the head! At least eat most of the bird if your going to kill it *sigh* Payday I am investing in motion lights and tomorrow I plan to have my husband start peeing around the coop and tree. I never in my life thought I would ask my husband to pee anywhere but in the bathroom. He is house trained though so I never have to ask him to do that just to clarify LOL Any other suggestion are always welcome.
