Some of my chicks had pasty butt at first and I heard they get that if they are too cold. I know that the chicks should be at like 90 degrees, but the farther end of their brooder box I have for them where the food and water is, is only at 75-80 degrees. What do you suggest I do to make it warmer? Also, my mom was the one who bought me the chicks as a suprise christmas present, and she didnt really know what to buy and stuff because she knows nothing about chickens. I know that red bulbs are suppossed to be better, but she didnt know and she bought me a 125w clear heat lamp. Should I replace this with a new bulb? The chicken guy at the feed store said they should be fine, what do you guys think? Thanks !
