I'm not feeling optimistic any more.
Lydia's hiding in the back of the brooder, has been all afternoon. I herded her from underneath about 5pm, to check her out, and her crop seems better. However, I can feel a sharp bone between her legs. It's as if she is shrinking in a matter of hours. I offered her food, she's not interested. I don't know how much more I can do, should do. I'm trying to help but she's not responding.
How old is she? I forget.
What's her poop like?
I'd make sure she's drinking. If the crop is still firm in the morning (check before she's ate/drank), then give the coconut oil, but then I'd also start treating as Sour Crop. Miconazole or Clotrimazole can be given. Give her 1/2 inch of the cream twice a day for a full seven days, even if she gets better, finish the treatment.
Hydration and then offer food. IF the crop feels impacted. Give 1 (one) stool softener (stimulant free), just pop the gel pill right into the beak. This can sometimes help break material up.
It all sounds like a lot, and maybe it is. I've done all of this with mine before and things have worked well. Sometimes there is very often an underlying condition that still needs to be addressed in order to resolve the crop problem. Worms, Coccidiosis and infection are the 3 more treatable underlying conditions. Reproductive disorders, not so much.
So start there, check her crop in the morning, if it's still full and hard, give the coconut oil, but work your way through the other treatment options. Try to get a really good look at her poop too.
You can have an impacted/slow and/or doughy crop and it be Sour too. Think of it this way - an impacted crop is relatively slow (or sometimes not moving much at all). Food/water can make it a bit doughy, but if it's not moving (slow) very well, then it's going to eventually turn Sour. SO! Just saying, some feel like they can only treat as "just impacted" then they move on to "just doughy", work on it as a whole. Does that make sense?
