I was recently diagnosed with babesia and lyme disease .I have 14 hens but would like to get some guinea hens ,I guess as added protection for my children.I heard they are great at eating tics even the little deer tics. How will my hens take to them .I heard they are pretty self sufficent,roosting in tress .Will they eat the layer feed eventually?What starter feed do I use. We were going to let them free range but build them a seperate pen and quarters.How will the hens take to them I know they get quite big will they bother my layers ? I have several breeds RIR,BARRED ROCKS,sex linkes , Old english, Easter eggers,They are about 1 yr old.We have 3 acres whats a good # to start with??We plan on putting them up @ night.We free range the girls while were home but I would like to leave these out if possible as much as I can ,how are there protective instincts??
