Lethargic, heavy breathing, and odd eggs

[Dominoes]

Help. 1 of our 2 chickens is sick. Eggs over the past week are odd colour and shape. Last egg was 3 days ago. The Last 48hrs she's been lethargic, just sitting down all day in 1 place and breathing heavily with eyes half closed. Comb looks nice and red, feathers look glossy and she's been preening and puffing them out. It's spring here and we've had 2 sunny days. What might be wrong and what should I do?

Welcome to BYC.

How is your hen?
How old is she?
What type of food/treats do you feed?
Can you post a picture of the odd eggs?
How does her abdomen feel - soft, hard, normal, bloated, fluid filled, etc.?

If she is lethargic, then she could be egg bound or have some type of internal laying/reproductive disorder like Egg Yolk Peritonitis, Ascites, tumors or cancer.

Vet care would be best.

Soak her in a warm bath with epsom salts. Gently feel inside her vent about 1" with a lubricated finger, feel if there is an egg inside.
Offer her some extra calcium like TUMS or liquid calcium if you have it. Keep her warm in a quiet darkened area and make sure she is staying hydrated. If you have some poultry vitamins add those to her water.

Let us know how she is doing.
