Think of the amount of light that you get on cloudy/ rainy days which could be about 50% of a sunny day. On top of that, they also have a tarp over their heads... another decrease of light which is not good for appetite. If the birds are also piling up at night in a corner and pooing all over each other says that they are cold too. So a heat lamp is in order as they are expending a good portion of their feed intake just to keep warm. Then they spend a good portion of their eating time on feather preaning to get rid of the dinginess and general feather upkeep in their desire to keep warm, and you have another oportunilty for weight loss. Not good for growth. Remember the old Scottish proverb... " the eye of the master fatens the cattle!". Good luck.
