My juvenile goose sometimes acts like she has trouble swallowing. She has been eating and drinking good but acts like she is gagging at times. I believe that she has a lump at the top of her neck that I don't notice on my gander. I have tried looking down her throat but can not see anything stuck in there. I have felt her neck/throat but can not really feel anything but at times she seems to have what appears to be a big bump right at the start of her throat. Has anyone experienced anything like this. At times she appears to not feel well and goes back to the chicken house or run to rest. Thanks.
