Wow, thanks, all of you, for all this information. It's alot to consider all at once, but I'm ready!
Ok ... so stopping her egg production will help but does not diminish the importance of getting rid of those egg yolks/fluid, especially since this is the summer? Makes sense. I think you're right, Barbara; I read somewhere that sometimes the egg yolks can be absorbed, although I think my hen is past the point where I could just stop her from laying and let her absorb the yolks. I think the strain on her system will get to her too quickly unless I get rid of some of that fluid. She may have absorbed some of the yolks, though, or at least she was standing less upright today and was more active both yesterday and today, and she's sleeping on the roosts tonight. But, she still doesn't look great, so I'm going to have to get that fluid out of there. Is there a difference between draining the abdomen and getting rid of the egg yolks, or does draining just get rid of the fluid around the yolks but ultimately leaves the egg yolks sitting in there? (I'm sorry if these are dumb questions; I'm a little new to this whole internally laying thing.)
So I take it I need to do three things: one, get rid of the fluid inside; two, stop more yolks from accumulating by stopping egg production; and three, change her diet so it won't encourage laying. Although it is a recurring problem, will it eventually, if she lives this long, stop being an issue once she is too old to lay anymore?
Looking at the chart (btw, thank you
@casportpony !), I think she's on the scrawny side. So, should I still go ahead with the reduced feed or not? She really likes eating the soggy layer food from the ducks' bowl and snacks on that throughout the day. She acts like she hasn't eaten all morning when I let her have access to it.
Their layer pellets have 16.5% protein, but I can get poultry grower with 15% protein, which obviously would have a lower calcium level, so I'll go with that instead.
