MOST of what my chickens eat doesn't move. I wouldn't worry about that AT ALL.
Sounds like a good place for a fence 1" inside the lot line.
100'??? Geez, our last house was on a lot 44x100'. Still would have had to get permission from the neighbor if we wanted chickens though (5 max, no roosters), the requirement is that the coop has to be 20' from all lot lines unless the neighbor agrees otherwise. Kind of hard to do with a 20' x 44' back yard. I think a coop 4' wide and 0' deep would be too small for more than 3-5 chickens
Instead of a variance, I would see if you can get enough signatures on a petition to CHANGE the zoning regs to seriously reduce the setback. Lots of times the regs are made by people that don't know SQUAT about what they are regulating. For instance, in Minneapolis (I think it was) you are REQUIRED to keep your coop at 34F or higher year round. There is not a single reason to do that. Chickens can easily handle temps 40F lower than that. More than likely these well meaning regulators are killing chickens by the bushel basket with people building well insulated, nearly airtight coops so they can keep the temp up. No ventilation, the chickens will die from the ammonia. No ventilation, the chickens will suffer from high humidity. Small enough to heat cheaply, not anywhere near enough room for the chickens. Obviously SOME people would fork over the money to keep the temp up in a more open coop but I bet that is a minority.
Sounds like a good candidate for a wireless electric fence. I really don't like to see dogs tied up.
No reason to keep them out of the compost pile! They will only eat things they want and they stir it up a bit. When you think about it a real deep litter coop or run IS a compost pile.
Um, you do realize that when the chicks are 4 weeks old you will need to move them to your house and REPLACE them with new ones at your Mom's!!!! You can't just tease her with chicks for a week or two.
And why is she feeding them M&Ms?? :/
Nope, Blooie is NOT the brightest crayon in the box, we ALL know that! Heck she's told us enough times over the past 3 years.
Mom's still got it! Nice way to find that out.
Yep, "the old bat" is a phenom. How many 80 year old women go up on the roof to clean the chimney??
