Hi,
I'm really glad to hear that you rescued those poor hens from the commercial operation and I hope they start laying for you soon. I'm sure they will start laying, it's just a question of when.
I find it's very expensive to feed chickens so I can understand your problem. I'm always looking for ways to make it cheaper without sacrificing the food they need. I just had my DH make up new feeders out of empty cat litter buckets. He cut out holes in the sides, but not too near to the ground. But low enough that they can reach in and eat and get to the bottom if necessary.
I find keeping the openings as far up from the floor/ground as possible makes it less likely that they will kick foreign matter into the food. It was getting so bad with my old feeders that every now and then, I just had to throw everything out and start over with fresh food, which is so wasteful.
It also seems like they waste less (by billing out the food) with the feeders DH has made. And the feeders were free!
I think pellets are less wasteful than crumbles but, unfortunately, I have a group of 4 hens that won't eat anything but crumbles. So I am stuck with buying them just for those 4 hens.
I can't, but if you are able to free-range in your location, that should also help with the feed bill. As soon as the grass grows and the insects come out, anyway!
I do believe that they will need a period of adjustment, coming from a commercial farm. I just hope it's not too long for you.
Good luck!
