Nearly all non-mammal vertebrates have nucleated red blood cells (nRBC). Non-nucleated RBC's are a unique feature to mammals. There are of course a few notable exceptions, such as the artiodactyl order, which have an odd blood morphology.
No, mature red blood cells of chickens do not have a nucleus. They lose their nucleus as they mature in order to make more space for hemoglobin, which is essential for transporting oxygen. This allows the red blood cells to carry more oxygen efficiently.
Frogs have nucleated red blood cells, whereas humans have anucleated red blood cells. This means that frog red blood cells contain a nucleus, while human red blood cells do not. Additionally, frog red blood cells are elliptical in shape, while human red blood cells are biconcave disks.
Areolar connective tissue contains various types of cells, including nucleated cells such as fibroblasts and immune cells. However, loose connective tissue is a broader term that encompasses various types of connective tissues, some of which may not contain nucleated cells. Examples of loose connective tissues without nucleated cells include adipose tissue (which primarily consists of fat cells) and cartilage.

RBC of all the mammals is anucleated without any exception. RBC of mammals are nucleated only during embryonic stages. It's just that RBC's of camels and llama are oval in shape and anucleated.
Yes, birds have nucleated red blood cells.
The red blood cells of all mammals, without exception, are anucleated (lacking a nucleus). Mammal RBCs are nucleated only during embryonic stages. The red blood cells of camels are oval instead of round so they can withstand the effects of water deprivation better.
llamas are camelids. Camelids can have a small number of nucleated red blood cells. But their red blood cells are elliptical rather than round.
A reticulate red blood cell, or reticulocyte, is an immature red blood cell. In mammals, reticulocytes do not have a nucleus. They are slightly larger and appear more blue in colour (with standard stain) than mature red blood cells. A nucleated red blood cell is one which contains a nucleus. Mature mammalian red blood cells do not have a nucleus. In mammals, nucleated red blood cells are more immature than reticulocytes - and are not normally seen in peripheral circulation. They can be a sign of anaemia if seen on a blood smear. Birds and reptiles have nucleated mature red blood cells.

Reptile red blood cells are nucleated, meaning they contain a nucleus, unlike mammalian red blood cells which are anucleate. Reptile red blood cells are also oval-shaped whereas mammalian red blood cells are typically circular. Additionally, reptile red blood cells contain different types of hemoglobin compared to mammals.
NRBC stands for Nucleated Red Blood Cells.

NRBCs (nucleated red blood cells) are immature red blood cells that still contain a nucleus, typically seen in the blood of infants or in certain medical conditions. Reticulocytes are also immature red blood cells, but they have lost their nucleus. Reticulocytes are released from the bone marrow into the bloodstream to eventually mature into erythrocytes (mature red blood cells).
