l was wondering cause I just read about someone wanting to try hatching pigeons and pheasents and other birds from there chickens. If she did this would it really be ok. Also would those birds think there chickens.
Chickens can be the silent carriers of black head and this disease can kill your turkeys. As for guineas, they are a more dominant type of bird and can get very aggressive against chickens if they feel like it. However, with enough space, if they cross range while free raining or in a large barn, people have kept them together. It is not generally recomended you keep different types of fowl or poultry together.
The birds you want to stay away from your chickens are wild ones as they can carry feather lice and mites which are transmittable to your birds too.
If they try and hatch pigeons they will die amidiatly because they are altruicious and chicken precosious meaning that pigeon babies need to be fed and chicken babies find their own food. I would also agree that you should keep turkeyes and guineas away from hens.
Yes, blackhead is more of a problem for the *turkeys*, not for the chickens from whom they can catch it. OTOH the turkey version of Marek's is actually arguably a *good* thing for chickens to catch, as it does not cause tumors to form and acts as a sort of natural vaccination helping the chickens resist other, nastier 'chicken' strains fo the disease.
