Clear Eggs

When a pair of birds produces eggs, there are two parts - the egg itself created by the hen [with the shell, yolk, and white (albumin)], and then
the sperm created by the male bird which fertilizes the egg. If an egg has no yolk, it means there is a problem with the hen. If the yolk is
present and the parents are brooding but the egg never gestates, it could mean there is a problem with the male. Either problem could be a
sterility issue, but could also be a nutrition problem, or "not quite in condition" problem and the birds haven't raised their internal temperatures
to incubate the eggs..

Clear eggs are eggs that have no yolk and are infertile. This could be caused by something as simple as incomplete copulation, or it could be
a more serious problem caused by improper breeding condition, poor nutrition, or a lack of calcium or vitamin D3 in the proper ratio with
phosphorus. Proper nutrition should solve this problem, but if you are still having problems, separate the pair and allow them to wait another
season before trying again.
