Thank you. I think ill take over their care for the next 2 weeksChicks need enough room to eat, sleep, romp, play, stretch their wings,learn to roost, and freely choose a warm or cool spot. Crowding too many in IS detrimental. Crowding can cause bad eating behaviors, pecking, disease, overheating and cannibalism. Average brooder gives about 2 sq ft per chick until they are fully feathered. Then it ups to 3 until they are ready to go to the flock.
