We just bought some duct tape the other day so may use that.

although mine doesn't seem to stick too well.

have it stuck to cardboard and it seems to come undone and.had it on a pillow case seem and it ended up coming undone and trapping a chick.

that was partially my fault though as it was a middle seam pillow case and.another chick had gone.up day before but i assumed the duct tape would hold strong. Was wrong about that. Little chicky went in apparently and I checked back, found she was missing, found her in the.pillow case (and another chick followed me in while i rescued her ha) and so I pulled MHP out to get her out and found that the duct tapr had not.only come undone but also twisted and was stuck on her wing. Poor thing.

thankfully I only had the pad on 2 though as they're currently inside or I am sure she would have been burned. At first I stupidly ttied to pull and got one small part off (and.some down) but I immediately realized that pulling was BAD and had my mom get some olive oil and then the main part that was stuck (caude the other was just a little piece twisted on top) came right off after getting some olive oil on top of the wing, op tape, and down in between wing and tape. Came right off. Before I found this one.another also had a small piece of tape on her back that I foolishly just pulled off as this was before I thought of the oil idea. Never again. Luckily though both chicks are doing fine and no worse for the wear. I also immediately found a pillow case with an end opening rather than middle AND it zips so super success. I really really do not understand why the tape didn't stick though. We used to have duct tape and it was impossible to get off. This was just ordinary kind, not outdoor or extra strength (though we did also buy outdoor. Will try that and maybe buy extra strength) but it IS the actual "duck tape" brand or whatever, not a knock off. They also apparently have Gorilla tape so maybe will try that. Was amazed the duct didn't stick though and.it hardly feels sticky. Very odd.
