There's a book on natural land management published in the 50's which is now online, it was my inspiration of using animals to manage land rather than expensive machinery. Originally we were looking for inexpensive ways to clear a portion of our acreage, but that quickly changed once I began pulling ticks off of me and our dogs. So pest control became the focal point. The spousal unit and I went to a "chickens 101" course and knew the moment we left that chickens, ducks and geese were in our future. So here's a quick list of pro's and con's from our perspective, your mileage may vary ;-)
PRO's:
Yard spiders, ticks, and other creepy crawly pests are being quickly and efficiently erradicated
No longer need to cut the grass in the back yard (not sure if this is a pro or a con right now)
The compost bin is over flowing, had to construct a second one and all the flower beds / garden will be very happy next spring
I've got 11 new friends, each with their own personality and quirks.
They make me smile and I look forward to going out and working to make their lives better
Natural stress reducer
CON's:
Frogs, salamanders, skinks and other small animals don't stand a chance (not sure if its a con or not, but the first time we saw first hand how a young duck could catch a small garden snake and proceed to consume it whole... we, it leaves ya speachless I'll say that!)
When you lose one, it's crushing
They can be very hearty and very fragile at the same time.
Not high maintenance, but there is some. There are no free lunches
Mistakes will be made. (which to me is a PRO, because then learning takes place and I become a better provider)
Both lists are much longer, but that's what comes to mind in just a couple of minutes. The people here have blown me away with the quality and level of responsiveness, helpfulness and willingness to correct an errant way or choice. I tried a couple of other forums and this one by far is the best I've found.
While we do have chickiens and geese, they serve their own function, but the majority of our flock are 6 Muscovy ducks which are reflected in most if not all of my list of pro's and con's.
Hope this helps and best of luck no matter what you decide!!
