I'm new to the whole backyard chickens thing- been doing a bit of reading, but the main obstacle for us is our dogs. We're in central Arizona (county land, unincorporated area), and would like to keep chickens on grass. I've been looking at a number of "tractor" designs so we could move them around- wouldn't want more than 2-3 birds. I don't think we could consume that many eggs, really. Anyway- we also keep greyhounds. While some are pretty laid back, we have one that is an absolute terror when it comes to anything that's not another greyhound. We had some ducks land in the backyard once- holy heck. We didn't hear the end of that from Miss Whines-a-lot until half an hour after they left. However, she does get kind of used to critters after a while; we have some gerbils in another room, and she's no longer homicidal about those. Aside from the obvious safety questions when it comes to keeping birds (I am confident I could construct a coop that would keep her out), would it be stressful or otherwise harmful to cooped chickens- particularly if they started out as very young birds- that might be exposed to a greyhound like that? The greys are inside 99.5% of the time, but I'd rather not keep birds if they'd just be stressed out for that 0.5%. We don't have enough room, I don't think, to fence off part of the yard with an opaque fence. Any suggestions would be welcome. Fresh eggs would be great, but I'd like for the birds to be treated well.
