Well, that's factory farm type spacing, most here want better conditions and have learned that crowding has many drawbacks and problems.I’d always read 2 sq. Feet per chicken, which would mean ours should hold 4 fine (assuming the rule of thumb here is correct).
Could very well be.Is it possible they’re still adjusting to their new home after 2-3 weeks?
You got 1 year old birds from a hatchery?
