We recently got into raising chickens and guineas. We have 15 guineas. (Well, 14 now) I have a couple of guineas that are worse about bullying the others, but we recently started free ranging some young chickens. (Black Australorps and Barred Rocks) 1 or 2 of the guineas immediately attacked these young birds very violently. It was pretty disturbing, but also kind of funny. I have been accused of being the chicken whisperer around here, but my wife sure went into Crazy Chicken Lady mode when those guineas attacked her babies. The guineas were way faster than she is, so she couldn't catch any of them. Good thing too, because I have no doubt she would have killed them with her bare hands! She doesn't usually cuss, but the 4-letter words were flying that day. Anyway, we got them all back in their respective coops for the night and I decided that I would be ready the next day. We let them all out again and sure enough, 1 of the guineas attacked the chickens with a vengeance. I took him out with a .22 rifle and we had him for dinner. Guinea really is delicious. The rest decided maybe they didn't want to attack any more that day. In the last couple of days, a few of the other guineas are still bullying the young chickens, but not as badly as at first. They never bother the larger barred rocks or buffs at all. In fact, my barred rock hens rule the roost around here. I'm just wondering- are guineas better at keeping ticks and other insects down than chickens can? Guineas are thugs and bullies compared to chickens. I just wonder if it's going to be worth it to keep them around long term and the pest control factor is probably a big decider for me unless someone has some other points I should consider. I'm out on some land, but I have people coming and going regularly. They must be used to this, as they don't tend to make any noise when cars come and go. They mostly make a huge racket when they see me doing something they're not used to seeing me do....or when I have some food for them. Not the best security alarm when I'm the one they alert on the most. Thoughts? Thanks!
