Feed inside the coop or outside?

I understand what your original question was. But since you are fairly new to owning chickens, I thought I would take the time to explain why your choice of feeds were somewhat inappropriate for your flock. Good nutrition is an important part of raising a healthy and productive flock.
What you are feeding is more important than where you set the feeders.

 

I am terrified now reading this post as I was advised to feed my bantams layers after 20 weeks old or so whichiI did but I'm also aware they may not lay again until spring. I have two plastic waterers and found they need less maintenance when kept inside as when kept outside they turn green quickly.

 

This is not my opinion for feeding layer feed. This is a quote from Nutrena poultry feeds
Is it OK to feed layer feed to chicks?
Layer feed is not properly balanced for chicks, as it will contain too much calcium. While one or two feedings should not cause a problem, a continuous diet of layer feed to chicks is NOT balanced for proper growth, and chicks may also experience kidney damage.

 

I keep my feed inside the coop to keep it dry and to try to keep the wild birds and other critters from eating too much, for smaller coops there are some nice PVC feeders that can be made.

 

We have feed inside. Don't want the mice getting in it at night.

 

I'm just making my girls some oatmeal for the morning. Our weather is crazy unpredictable and we haven't had a really cold morning until now. So, I thought I'd get a little more precise if you want to give your girls oatmeal. My two handfuls equaled out to a heaping 2/3 cup of oatmeal. And cooked it in the microwave for 1:15. This time I added in some fruit since I had some for my kids last night to go with dinner and they didn't eat it all.

 

I keep feed and water outside of coop. It matches my management of opening the coop door every morning and not locking chickens in coop during cold weather. The use of tarps for corner or sides of prevailing wind makes for the wind shield to protect birds. It's virtually same temp as in the coop and they prefer to be outside unless there is snow on ground in which case you need to shovel it and put a thin layer of hay down or they don't want to walk on it. You can make a small stand and hang the feed under it, I always have coops on stilts so feed and water are under coop. Feed should be brought inside each night to deter attracting larger animals and rodents from feeding unchecked.

A system of rodent control should be in place in the beginning of raising birds. Rodent populations will get out of control and that's no fun. Systems for drowning rodents or snap traps in protective container work well enough if started in the beginning. Otherwise chunx bait in tamper proof boxes is really the best way to eradicate them. Never use poison pellets, they get strewn about as the rodents drop them going back to nests. Chunx has to be chewed off so it fits in cheeks, brought back to nest where kits and adults die there.

This is the bait and locked bait box (tamper proof) I'm talking about. I have one of these in corner of run at all times unless chicks are in there. Image is copied from google images.
