Our 15 RIR chicks just arrived an hour ahold before putting them in the brooder it was up to 101 directly under the light. They are in. The garage so I figured I would leave it due to it being cold here. I put the, in and they' re all huddled, even though it's 100. Are they trying to acclimate due to them being shipped in the cold or could it be stress? I know it's warm under the light and even just outside the light it's 95
