We have 3 litters in our colony. Once the babies started coming out of the nest boxes I sectioned off an area in the run so that the chickens couldn't get to the babies while they learned to hop around. We found a baby that had been trampled on Sat. I assumed that they didn't have enough room and let everyone have access to the whole run (the babies are getting around very well now). Yesterday I found 2 more that looked to have been trampled. So I moved the babies into their own area. I gave the mamas supervised time with the babies last night and today and none of the mamas are letting the babies nurse. The babies however seem to have no problem eating the pellets and drinking water. When I put a couple of dishes of pellets in the nursery run this afternoon they attacked it! Could the mamas be weaning the babies? 2 litters are 4 weeks and the other is 3.5 weeks. It just seems too early but I am still pretty new to this.
