Hello... just today one of my hens started heeeeee--hawwww... over and over again. It's pretty loud. She's been doing it for maybe two hours. It took me forever to figure out what it was (we have a lot of crows/magpies here). I haven't been able to catch her. I gave them some egg shells this morning.. but they weren't as finely crushed as usual.. could a piece be lodged in her throat? We have ducks also.. first time duck owners. They share a tremendous penned in area, which they are only in at night.. free range during the day. We have separate feeders/waterers.. but they tend to share. Could this be linked? She is about 5 months old. Hasn't started laying yet (my flock of EEs are the same age and none have laid yet.. but my 6 month olds have been laying prolific amounts). Any ideas??? If it is a gapeworm... can I order de-wormer form the vet? I'm in a tiny bush town.. I'd have to have it flown in. Maybe this is a sign she is highly infected? I'm going to go check on her again. Thanks to all!
