Per-bird feeder and water figures
| Figure | Amount | Source |
|---|---|---|
| Feeder, general | at least 3 in | Penn State Extension per bird. |
| Feeder, small birds | 1 in | Penn State Extension linear inch per bantam-size bird. |
| Feeder, large birds | 3-4 in | Penn State Extension. |
| Feeder, laying hen or meat bird | 2-3 in | Maryland Extension. |
| Drinker | 2-3 in | Maryland Extension per bird. |
| Nipple waterer | 1 per 6-8 birds | Penn State Extension. |
| Five-gallon waterer | up to 75 hens | Maryland Extension. |
| Flock over 25 birds | separate feeder areas | Penn State Extension. |
Inches of trough and pounds of feed answer different questions. Minnesota Extension says a 6-pound hen eats roughly 3 pounds of feed each week. That weekly weight is how you count bags. It is not a substitute for the 3 in of feeder, and this page does not turn either figure into a price. The cost guide linked above is the place for the bill.
Daily gallons are a separate question from these inches. The water page runs a flock through the feed calculator and then applies the published gallon rates.
A flock can be under the five-gallon limit and still need more than one nipple. Maryland Extension stops the five-gallon waterer at 75 hens. Penn State Extension starts a new nipple every 6-8 birds, so 30 hens are still one waterer and 4 to 5 nipples. Drinker lip space is its own measurement: Maryland Extension wants 2-3 in per bird, the same band as its feeder line, not the nipple count.
Worked flocks
| Hens | Penn State feeder | Maryland feeder and drinker | Nipples | Separate areas |
|---|---|---|---|---|
| 6 | 18 in (1 ft 6 in) | 12 in (1 ft) to 18 in (1 ft 6 in) | 1 | No. 6 is not more than 25. |
| 10 | 30 in (2 ft 6 in) | 20 to 30 in (20 in (1 ft 8 in) to 30 in (2 ft 6 in)) | 2 | No. 10 is not more than 25. |
| 25 | 75 in (6 ft 3 in) | 50 in (4 ft 2 in) to 75 in (6 ft 3 in) | 4 to 5 | No. The rule is more than 25. |
| 30 | 90 in (7 ft 6 in) | 60 in (5 ft) to 90 in (7 ft 6 in) | 4 to 5 | Yes. 30 is more than 25 (Penn State Extension). |
Feeder inches are the hen count times 3 (Penn State) or times 2 and times 3 (Maryland). Nipple counts round the count up from hen ÷ 8 and hen ÷ 6. Six hens fall under one nipple because 6 is the start of the 6-8 bird share.
How to size it
Choose the bird size before you multiply. Bantams take the 1 in line. Standard layers take 3 in, or 2-3 in. Large birds take 3-4 in.
- Standard feeder. Hens × 3 in (Penn State Extension). Hens × 2 in and hens × 3 in (Maryland Extension). For 10 hens that is 30 in, and 20 to 30 in.
- Bantams. Birds × 1 in (Penn State Extension). Ten bantams are 10 in, worked in the breed-size section.
- Large birds. Use 3-4 in rather than 3 in (Penn State Extension).
- Nipples. Divide the flock by 8 and by 6 and round each result up (Penn State Extension). Ten hens: 10 ÷ 8 = 1 with a remainder of 2, so round up to 2 and 10 ÷ 6 = 1 with a remainder of 4, so round up to 2, so 2 nipples.
- Five-gallon waterer. One covers the flock when the head count is 75 or under (Maryland Extension).
- Separate areas. Only when the flock is more than 25 birds (Penn State Extension). See the 30-hen example for a flock that crosses the line, and the past-25 section for the count that sits on it.

FAQ
How much feeder space per chicken?
Penn State says at least 3 inches of feeder per bird, 1 linear inch for small birds such as bantams, and 3 to 4 inches for large birds. Maryland says 2 to 3 inches of feeder per laying hen or meat bird.
How much drinker space per chicken?
Maryland says 2 to 3 inches of drinker per bird. Penn State sizes nipple waterers at 1 nipple per 6 to 8 birds. Maryland says a five-gallon waterer can accommodate up to 75 hens.
When should feeders be in separate areas?
Penn State says flocks of more than 25 birds need feeders in separate areas. A flock of 25 is not over that line. A flock of 30 is.
How much feeder for 10 hens?
10 times 3 inches is 30 inches on the Penn State rate. 10 times 2 to 3 inches is 20 to 30 inches on the Maryland rate. Nipples round up to 2, because 10 divided by 8 and 10 divided by 6 both round up to 2.
