Hi,
my cockatiels have laid 6 eggs.I have gone to cockatiel cottage and read up on their hatching and feeding instructions. What is a crop in the chicks mouth? (I assume) Please any help in this matter will be appreciated. also, I'm going shopping to get any items I need for when they hatch..I'm not sure I have everything.At my math they should be hatching around the 15th of Dec. All help would be appreciated.
Thanks

Call your vet, or go to the pet store where you obtained the birds -or any pet store that sells this kind of bird. They should be able to point you in the right direction.
