I don't mind worrying unnecessarily. 9x out of 10 it turns out nothing but the 1x out of 10 problem makes the worrying and watching worth it. If a hen doesn't improve in a couple hours I take them into the kitchen to watch them. I have a Silkie that has respiratory issues and if she's not acting spunky I immediately go into "watch" mode. If I didn't worry, I'd have a dead chicken by now. Glad your girl showed improvement!
I feel pretty lucky that this time it turned out to be nothing much to worry about. She wound up laying the biggest eggs she's ever laid...2.22 ounces vs her usual 1.87 ounce egg. I think she may have just been overwhelmed by the size trying to exit her bum. Since laying she's been playing quite merrily in the water I allow to run out from the hose to give them a small "stream" to play in.
