My chicks go on shavings around day 3-4. I am sorry to hear about your chicks, Kristina, and do not want to start anything, but having chicks on shavings for 20 minutes would not kill them. Even if they ate all they could possibly stuff into their crops, 20 minutes later, they would have impacted crops and waste away over a period of 2-3 days if not treated. If the chicks were dead in 20 mintues there had to be something else that caused their death. Overheating, toxic fumes, anything else environmental that the lucky two were removed from before they succumbed to it as well. I just don't want other people to have a fear of using shavings when they are perfectly safe.
