Baby Birds in Brooder

The birds - guinea fowl, chickens, ducks, geese and a lone turkey - are about a month old. In a week or two they'll have enough feathers to stay warm at night and I'll move them outside for the summer.  I'm counting on the guineas to eat enough ticks to spare me from Lyme disease.  I find myself checking twice a day for ticks; at this point I've only found 3, but I think there will be more as it warms up.
