Okay well at this point what ever she will eat. Mine won't touch dog kibble but my ducks and chickens love it they eat the Diamond lamb and rice. I sure was hoping casportpony would have replied by now, but if your going to take in a stool sample that's even better the vet can prescribe dose and wormer.This year Gracie has been laying an egg maybe once every 2 days or so. I'm waiting to collect a stool sample from her.
ps.. she used to eat the dog's food all of the time. I tried tossing her some Iam's senior lrg breed kibble. Score! She gobbled it up.
Keep us updated on how she is and what you find out.
Laying an egg every other day is the norm for geese so she is perfectly normal there.
