A 24-bird broody mother breeds flock in Mountain & High Altitude conditions is one of the more specific planning challenges in backyard keeping. The breed-purpose requirement (natural hatching) must be balanced against the climate constraints of Mountain & High Altitude: winters to -10 to 20 F, summers to 80-90 F, with 15-30 in of annual rainfall.
Recommended Breeds for This Combination
From the Broody Mother Breeds category, the following breeds perform reliably under Mountain & High Altitude conditions: Silkie, Cochin, Asil, Old English Game, Buckeye. The primary climate concern — altitude stress — narrows the field considerably.
These breeds have limited foraging instinct, which in Mountain / High Altitude means you should budget for near-full commercial feed coverage rather than relying on pasture supplementation.
Coop and Run Specifications
For 24 birds of this breed category in Mountain & High Altitude conditions:
- Minimum coop interior: 72 sq ft (3 sq ft per bird)
- Minimum run: 240 sq ft (10 sq ft per bird)
- Nest boxes: 6 (one per 4 hens)
- Insulation: 2-inch rigid foam on all walls and ceiling — R-12 minimum in walls, R-20 in ceiling
- Ventilation: 48 sq in of high ventilation minimum (above roost level)
Feed and Water Requirements
Daily feed consumption: approximately 6 lbs total (0.25 lbs per bird). Annual feed budget: $600-900. Layer pellets or crumble at 16-17% crude protein is appropriate for this breed category; increase to 18-20% during molt.
In Mountain & High Altitude conditions, the watering challenge is frozen water in winter months. A flat heated base (60-watt model) or a submersed aquarium heater in a bucket connected to nipple drinkers is required in zone 4-7 (altitude-modified)
Seasonal Management Calendar
November-February: primary challenge month window. Altitude stress. Required management actions: confirm water heating is operational, check ventilation is not blocked by snow, monitor combs of single-combed breeds for frostbite.
Spring and fall transitions require inspection for external parasites (mites peak in late summer) and adjustment of light supplementation (if using artificial light to maintain winter production).
