I have 4 babys One is maybe 4 weeks, 2 are 3 weeks and 1 is 2 weeks When I got all of them they told me they were between 3-5 days.. They are all different sizes:/ 2 are black sextons?!!? 2 are RIR's.. They still have a lot more fuzz then feathers. They are living in a large dog kennel in the house with a heat lamp. I haven't let them out by themselves at all. I give them about a half an hour, I worry about others looking for a snack.. I don't want to do anything wrong, any help would be appreciated..
