@bgmathteach Butters has gained weight to 3lbs, 5 oz and has held it for two days. So she's gained at least six ounces. Developments in the last few days are that she seemed to be favoring the bigger crumbles, so I'd try to gather them in my hand when offering her feed, and today I got into town and got a bag of Nutrena Feather Fixer pellets,18% protein which would be good for Hazel and Popcorn to be eating because of the calcium.

So they all loved it, fed them out of my hands which Butters seems to like, and she stuffed herself on it this evening. She still favors the smaller bits, but she'll take a bigger one and break it up. She stopped to do some crop adjusting, I am hoping it just feels funny to her because her crop has not been filled like that for so long. Later I felt her crop and there was a nice firm ball of feed in there, comparable to Hazel's but a little smaller. This is new and good I think.
