I'm pretty sure one of my chickens is eggbound. The last time she layed was Monday (I'm writing this on Thursday*). Yesterday she started behaving a bit strange and jumped on top of the coop where there is a load of jasmin and honeysuckle hanging over creating a lovely shady spot. I thought she was just investigating, but when I looked closer she was crouched down and was doing her egg-laying noise and was shaking her head a lot. I'm not sure if she usually shakes her head while she's laying because she usually goes in her nest box. Anyway, no egg came (I've checked the floor around the outside of the coop). A bit later she went into her nest box and did her little noises again. She was in there ages, but no egg came. I also noticed that the pile of poo under the perch where she had slept was smaller than usual, so I watched her for ages to see if she did any poos in the garden. Eventually she did a small, runny one. This morning, there's only a tiny amount of poo under her place on the perch, and she still hasn't laid an egg.
OH has looked up the condition on the internet and some people say to lubricate the area with something like KY jelly (imagine going in a chemist and saying "Can I have some KY jelly for my chicken, please?"

). Other advice says to hold her over a bowl of warm water for a while. The problem with both is that since she's become egg-bound, she won't let us pick her up. She's a bngger to catch and if we do, she struggles and hunches her 'shoulders' making it really difficult keeping hold of her.
So, any suggestions please?
PS, I know the smilie is a duck, but it's as close as I could find to a chicken
