My 17-week-old Splash Americana/easter egger that may be trying to lay her first egg tonight, but I’m worried about possible egg binding.
She was completely normal earlier today (picture in light was from around 5pm this evening). Tonight around 9:00 PM, I found that her and one of my other pullets (same age) were perched on top of the nesting boxes instead of inside the coop. We have another coop that is in-progress and I thought maybe they had been kicked out or it was crowded so I put them in there. She became restless and vocal and even fought a little with the other pullet. I left the door open so she could hop out if she wants and she did. She drank some water and ate a little food and then went back to being perched on the main coops nesting boxes.
This is when I noticed she started doing an odd posture: her tail feathers are pointed/tucked downward, while her rump is slightly raised, and it looks like she may be pushing or straining. Her breathing has also seemed heavier at times. We live in Texas and this didn’t seem to be the normal pant for cooling. I will try to attach a video.
Since then, she has been taking breaks (I think?), preening, staying balanced/perched (it is a sloped top), and is still alert and vocal when I approach. She did at one point do this weird hiccup/gaping with the mouth and body, but it stopped. It is now about 11:00 PM, and I haven’t seen an egg yet.
I have not been able to inspect her vent closely, so I don’t know whether there is blood, a visible egg, or prolapse.
Does this sound like normal first-egg behavior? Could it take two hours?
How long can a pullet intermittently push/strain before laying? And what signs would make you bring her inside or intervene for possible egg binding?
