Can I use a deer feeder to make sure my chickens get plenty of food while I'm away? It be simpler to have the pet sitter check/collect eggs, w/o going into the coop (I have nice roosters but there's always the first time) How do deer feeders work? The one's I'm looking at are 44/50 gallons and have timers on them... It would be on the wooden deck part of my coop under shade/weather proofing- My enclosure is rat proof (so far). ---- I have an auto water bowl- and a kiddy pool and would put out gravity waters also- just in case. --- What are good prices for these units? What won't fit out the feeder/spreader thingy?
