i collected my eggs as usual this morning but with them but this tiny little white egg, looks like a quails egg, they must have laid it as it was with the others and no other birds can get into the house etc. is this normal?

It sounds like a wind egg also known as a fart egg or a witches egg. Nothing to worry about, some are yolk less and others have just a tiny speck of yolk

2 possible reasons, just an odd mistake within the birds prodcution line in the body nothing to worry about does happen ocassssionally she may however do it rarely again. Or if the bird is young and just starting to lay then the birds body isnt used to egg production and is just getting itself sorted for next spring, its just a pullet egg
