Even though Blue Cuckoo Marans are hardy, disease-resistant birds, proper care is essential. Your birds require food, water, and shelter to meet their nutritional and housing needs. Whether on the range or confined quarters, you must feed and water your flock daily.

Here is a breakdown of the nutritional and housing requirements for Blue Cuckoo Marans chicken:

Feeding & Nutrition

Blue Cuckoo Marans do not have any distinct dietary needs. They eat the same food as any other chicken breed.

Afterward, you can provide them with a protein-rich diet for optimal growth and development until they reach 18 weeks before changing the diet.

Adult Blue Cuckoo Marans do not require much protein in their diets unless they are laying eggs or molting.

  • Pumpkins
  • Corntops

  • Watermelon
  • Turnip
  • Lavender
  • Cornflower
  • Worms

Roaming birds can forage food for themselves, but you place waterers where the birds can access it easily. Ensure you keep chicken feed in airtight metal or glass containers to prevent vermin.


Housing is just as essential as chicken feed. Your flock requires a proper coop to protect the birds from predators. Since Blue Cuckoo Marans are large birds, the chicken pen should have adequate space to accommodate your fowls. It should have a waterproof roof and be draught-free to prevent common poultry diseases.

You can install perches and levels where your birds can sleep for the night. The coop should preferably have a droppings board for easy cleaning and hygiene. Ensure you vermin-proof the housing to keep rodents and predators at bay.

Blue Cuckoo Marans also require bedding in the coop. You can use locally available materials such as straw, old newspapers, hay, or sand for bedding. Layers need nesting boxes for laying eggs and brooding. Ensure there’s adequate lighting to encourage the hens to lay eggs.

Health Problems

Blue Cuckoo Marans are renowned for their disease resistance. They do not get sick easily, making them the ideal breed to add to your flock. However, their hardy nature doesn’t mean Marans don’t develop health problems. Your birds might become ill like any other chicken breed.

The secret to avoiding diseases is to vaccinate your flock. You can use water-based solutions and mix them with chicken feed or water. You can also dust your birds to kill mites, lice, and fleas.
