Okay, here is the frantic newbie asking for help again. I have already told you all that I got 10 babies from a dairy. I put them in the stall last night---it is about 8 by 16 ft. There are openings all along the steel roof between the rafters, although a great deal of the stall is tarped to hold in warmth, there are definitely enough big spaces for ventilation. This morning, I definitely smelled an ammonia smell when I went in to feed them. This is after only 12 hours! Do I need to use lime? Change the bedding? OR, and this is a worse thought---is there something metabolically or medically wrong with a baby or babies that I need to correct? Help please!
