The floor space to be allocated per bird will be determined by a combination of following factors:

1. The size of the bird at market age
2. Type of housing
3. Climatic conditions, and whether the farm is open sided or environment controlled

In general the following floor space allotments are recommended for broilers:

Non-insulated houses
1 sq. ft to 1.2 sq. ft. per bird depending upon the season and marketing weight.

Controlled environment houses (acclimatized)
0.4 – 0.6 sq. ft. per bird throughout the year depending on the size of bird at market age and the season.
