Hi all, Looking fr some guidance from anyone who has used chickens as a means of vector control on horse farms. We care for 5 horses on our 5 acres and I'm starting an experiment in the ideal number of chickens to control pests that are usually associated with horses/manure. Currently I've got 2 hens free ranging, 8 pullets in the "chicken mansion" learning where home is before we set them out to free range, and 9 more in the brooder. We live in Northern California. Horses all live full time in pasture with run in sheds. Has anyone found the right balance between enough to help with manure management but not too many that they will degrade the pasture quality? I'm anticipating losses due to predators (hawks) and although I don't like it, have come to terms with it. Thanks for your thoughts in advance!
