I have an 18 month ISA brown , 2 days ago I noticed she was in her box for a long time, She free range during day, she seemed to be trying to lay , later she had passed a very small egg. Doing same thing next day, I suspected egg bind, did an internall check but no egg seems to be stuck, I gave her a squirt of olive oil into her vent and about 10 mins later she did a HUGE poo, it was solid and a little dry. Its now coming up to 3rd day and she still seems to not be able to lay athough trying to. Ive done the warn bath, given her calcium. She is quite well, eating and drinking and pooing. But is trying to pass , her vent seems to be continually in the egg expelling look. Any ideas??
