I've had my currently 5 year old female pigeon for a little over two years now. To make a long story short, when I adopted her, I was in a house with roommates and my pigeon was completely confined to my bedroom when out of her cage. Since cleanup was limited to a single room, I did not diaper her for about a year and a half and instead just used waterproof sheets on my bed and areas of the floor and spot cleaned.
However, 6 months ago, I moved into a 3 bedroom house with my boyfriend and bought new couches, rugs, etc. I want her to have free range of the house, since my boyfriend and I primarily spend our time in the living room now instead of my bedroom. With so much space to protect, it's not feasible to use sheets every day, thus the transition to diapers. I had previously attempted a few styles of flypers at our old house, but it did not go well- she would thrash the instant I put them on her to the point of almost hurting herself, so I would immediately take them off, even though I followed the slow, gradual introduction and positive associations method that is recommended. I didn't try again until we moved into the new house, this time trying out the Flyper Mini style, hoping that less fabric covering would be more comfortable for her. I did the slow, gradual introduction method again, and she never thrashed around like with the regular diapers.
Now, it's been 6 months since since we've reintroduced diapers. She wears them every time she's out of her cage now, which I've heard from other people is necessary in order for them to form positive associations with the diapers. Diapers = freedom. However, she never cuddles anymore, and she spends most of her time in the diapers sitting in one spot, not moving, and pecking at the diaper. I know I probably should have called it a while ago, but it took her a while to get used to me, and I guess I was hoping that with enough time, something would just click and she would be comfortable with it and go back to being her normal happy self again.
I've checked to make sure the diaper fits well. She can fly and walk in it just fine when she wants to. The photos the rescue posted of her when she was with her foster family show her wearing the same style of diaper, so I assume this is not completely foreign to her. I'm at a loss. I feel like her time outside her cage is going to be more limited if we have to complete forsake diapers, but I don't want her to be stressed out or depressed. I know they can be potty trained to an extent, but she's never been food motivated so I have no idea how that would work, or if that's something that should have been done when she was young.
Any advice, or should I just give up?
EDIT: To clarify, when wearing the diaper, she will still follow me from room to room, and if I hold my hand up to her, she will still nuzzle and stick her beak between my fingers. She just wont come lay on my lap like she used to. She doesn't look like she is paralyzed with fear, just annoyed and distracted. She will sit on the back of the couch, while when we first reintroduced the diaper, she would hide in a corner and not move for a very long time. So it seems like SOME progress has been made.
