My 7 year old pigeon One-Eyed Jill laid a single unusually large egg a few days ago. Until this morning she acted very normal, spending about 90% of her time on the nest asleep (she likes to sit on the eggs, her mate Griffin does not). However this morning she has spent more time off the egg (which I swapped for a fake one,) and sitting on one off the two ledges in the cage. She's puffed up and standing with her head held close to her body, similar to how she likes to lay while on the nest. Occasionally Griffin does decide he wants to sit on the nest and to prevent him from throwing a fit (Griffin is very dramatic and tends to get his way) Jill lets him, when this happens he may sit on it all day. I have seen her eat and drink today. Jill is always a very laidback and lazy pigeon but tends to only fluff up like that while on the nest. She's always laid two eggs in the past. It may just be that Griffin wanted on the nest and Jill let him but was still in the mood to sleep like she does on the nest, but with her age and having only laid one egg and egg binding being serious I want to see what others think.
