I was outside late last night, actually about 2 a.m. My dog had been barking her head off, so I went to see what was up. Of course the dog barking woke all the roosters (and I have a LOT of roosters!), so they were crowing from their roosts. I have 6 baby silkies in a tractor with 3 BTW japs, and 2 OEGB pullets. I know 2 of the japs are boys, but the silkies are hard to tell. Plus the tractor gets covered completely with plastic at night. We have a light in there, to help keep them warm. I went walking through the yard, to see to my dog, and I heard the strangest crow! I was trying to think of which one sounded like that, when I heard it again!! It was coming from the TRACTOR!! It was actually a very good crow, for such a young chicken. I am not sure if it was a silkie, or one of the BTW japs, but one of these babies is crowing for sure!! And they are only about 3 months old at the most. Keep your that it does it again today, when I can see who it is!! It is impossible to tell which are boys and which are girls!!
