can this be done easily? We have only 4 layers who are now about 10 months old (will be 1 year in April) we hatched some eggs in November of 2011 (these eggs belong to our existing layers) and only 2 hatched. So we have two 13 week olds that NEED to go outside and I would just like to put them in with the older girls. The two young ones are that much smalled than our big girls so I was wondering if we put then in the coop during the night (roosting time) would that be okay? Will the youngsters be in any danger? We are actually bracing for a 'supposed' snow storm tomorrow, so was looking at doing this later in the week when it warms up a little. The lows right now at night are in the low 30's most nights. Oh, and they still have their lamp on over the brooder. It only has a 40 Watt bulb in it now, but they are also beside a wall heater.
