We ordered 10 meat birds who are currently just over a week old. I've noticed that 3 of them have short stubby wings and almost no tails, and the rest all have long wing feathers and most of their tail feathers in. My bantam chicks are the same - 1 has very stubby wings, no tail feathers yet, and the rest have long, long feathers. My daughters class hatched eggs last week and they also have 2 with short wing feathers and 6 with long wing feathers. Is this any indication of the sex of the chicks? Can we say the ones with short, stubby, almost no-feathers yet wings are male? Anyone else notice this with their chicks?
