I had a hatch a few days ago, well almost a week. Two were silkies and they both died. Both of them were fine and then one of them started off not walking and leaning to the side. I thought maybe she/he injured a wing. The other one I thought had splayed legs. But the first one died and the second immediately got ill and keeled over on his side. Then from the same hatch I had a RIR who did the same thing the next day. I then had three chicks left. Two barred rocks and one leghorn. This morning I checked the chickens and they were all fine. A few hours later, I noticed one of the barred rocks was tipping to the side and unactive. He died this evening. The other two still look healthy and they are the biggest ones of the hatch. What could this be? I have them in a brooder and the room is extra warm as well. Someone told me I just need to leave them in the incubator for a few days....whats your take on this? Second problem with other chicks: Also, I had a hatch of only a few eggs a few weeks ago. They are doing well, however, they look like they are going into molting already? The other day my friend gave me two leghorns and they look the same way. They are about 2 or 3 months old? I am so confused.....Is this normal?
